Abstract

Tanah dasar pada proyek pembangunan jalur ganda kereta api di KM 437+300 sampai KM 438+500 Gombong, Kebumen merupakan tanah lunak (N-SPT < 15) sehingga memerlukan upaya perbaikan tanah untuk menghindari terjadinya penurunan tanah melebihi penurunan tanah yang diijinkan, yaitu sebesar 20cm. Dalam penelitian ini direncanakan upaya perbaikan tanah dasar menggunakan Prefabricated Vertical Drain (PVD) untuk mempercepat proses pemampatan tanah akibat beban tanah timbunan badan jalan rel, beban konstruksi jalan rel, dan beban kereta api yang melintas. Hasil analisis pemampatan menunjukkan bahwa tanah dasar akan mengalami penurunan tanah sebesar 0,524m. Waktu konsolidasi alami yang dibutuhkan untuk mencapai derajat konsolidasi 90% adalah selama 268,9 tahun. Sedangkan, waktu konsolidasi untuk mencapai derajat konsolidasi 90% menggunakan PVD berjarak 0,8 m dengan pola segitiga dan segiempat adalah selama 15 minggu dan 18 minggu. Penanaman PVD pada kedua pola tersebut adalah sedalam 24 m

Abstract

Abutment jembatan merupakan bangunan bawah jembatan yang terletak di kedua sisi ujung jembatan. Proses pembangunan abutmen jembatan sering kali diperlukan adanya penggalian sampai kedalaman dasar abutmen agar pekerjaan penulangan dan pengecoran abutmen dapat dilaksanakan. Pada pekerjaan galian dalam, setiap sisi galian perlu untuk dipasang dinding penahan tanah tipe fleksibel (turap) terlebih dahulu.  Di dalam penelitian ini, dilakukan analisis kestabilan CCSP pada pekerjaan galian tanah untuk abutmen jembatan BH 1751. Metode perhitungan dimulai dari menentukan tekanan tanah lateral yang bekerja pada tanah, kemudian menentukan kedalaman penanaman CCSP yang mampu menghasilkan kestabilan CCSP terhadap gaya guling. Hasil analisis menunjukkan bahwa kedalaman penanaman CCSP yang memenuhi syarat keamanan terhadap gaya guling adalah 20 m

Abstract

The subgrade in the railway double track development project in KM 437 + 300 to KM 438 + 500 Gombong, Kebumen is soft land (N-SPT <15) so that it requires efforts to improve the land to avoid land subsidence exceeding the allowable land subsidence, which is equal to 20cm In this research, an effort to repair subgrade uses Prefabricated Vertical Drain (PVD) to accelerate the process of soil congestion due to the load of the railroad pile, the burden of railroad construction, and the burden of the passing railroad. Compression analysis results show that the subgrade will experience a land subsidence of 0.524m. The natural consolidation time needed to achieve a 90% degree of consolidation is 268.9 years. Meanwhile, the time of consolidation to reach a degree of consolidation of 90% using PVD spaced 0.8 m with a triangle and quadrilateral pattern is for 15 weeks and 18 weeks. Planting PVD in both patterns is as deep as 24 m

Abstract

Abutment bridge is a building under the bridge located on both sides of the bridge end. The process of building a bridge abutment often requires excavation to the depth of the abutment base so that the abutment reinforcement and casting work can be carried out. In deep excavation work, each side of the excavation needs to be installed in a flexible retaining wall type (plaster) first. In this study, CCSP stability analysis was carried out on earth excavation work for abutment bridge BH 1751. The calculation method starts from determining the lateral earth pressure acting on the soil, then determining the depth of CCSP planting that is able to produce CCSP stability on the rolling force. The analysis shows that the depth of CCSP planting that meets the safety requirements of the rolling force is 20 m

Abstract

In Indonesia, the dimensions of the rail steel profile have been determined by Minister of Transportation Regulation Number 60 of 2012. The commonly rail which used for 1067mm railway width is the rail type UIC54. However, the determination of rail profile type in Indonesia has not been equipped with an analysis of the rail profile strength to support the load acting on it. Thus, this journal will discuss the calculation of the UIC54 rail strength analysis to support locomotive loads of CC 203, CC 205, and CC 206. The calculation is using Beam on Elastic Foundation (BOEF) method which assumes rail behavior as a continuous beam that support loads above an elastic foundation. The value of UIC rail strength is written in the form of safety factors (SF). The calculation results show that the value of the most critical rail SF to support locomotive loads CC 203, CC 205, and CC 206 are 10.94; 8.93; and 9.67. The results of the rail strength calculation shows that the UIC54 rail is very strong in resisting the dynamic load of the locomotive and its cross section is too large to support the dynamic wheel load of the locomotive.

Abstract

Highly organic soil and peat are problematic soils due to their low bearing capacity and high compressibility. In tropical regions, the presence of woody material in these soils often affects the stress-compression and time-compression curves in load-increment consolidation tests, leading to unusual shapes. Consequently, conventional inorganic soil theory and the Cα/Ccconcept are inadequate for analyzing their compression behavior. As an alternative, the Gibson and Lo model can be used to obtain compression parameters from single-load consolidation tests. However, this method introduces considerable discrepancies when predicting the primary settlement. To address this issue, this paper proposes a formula for predicting the primary settlement in highly organic soil and peat in the field, especially in tropical regions. Samples were collected from several locations in Indonesia. The formula was constructed from the stress-strain relationship during the primary compression stage, obtained from numerous single-load consolidation tests. Long-term field settlement is predicted by combining this empirical equation for primary settlement with the Gibson and Lo model for secondary settlement. The proposed formula was verified using field soil monitoring data, demonstrating reasonable accuracy in predicting the primary settlement of highly organic soil and peat. Doi: 10.28991/CEJ-2024-010-11-03 Full Text: PDF

Abstract

Introduction: The Solo Balapan-Kadipiro elevated line project is considered to have a high risk of danger because the project is in direct contact with the highway and is located between residential areas. Hence, it can cause work accidents for employees or workers at the project site. This study aims to identify the risks of precast channel installation work, Geotextile installation. Method: Roadwork uses the Failure Mode and Effect Analysis (FMEA) method and carries out a risk control strategy to prevent work accidents in the work area. Risk identification in construction projects is carried out based on field observations and risk observations in the hazard identification risk assessment and risk control (HIRARC) documents and job safety analysis (JSA) documents prepared by HSE, to be further validated through a preliminary questionnaire to respondents. Furthermore, the respondents assessed the Severity, Occurrence, and detection levels by filling out the main questionnaire using a predetermined rating scale. Result: risk analysis using the FMEA method shows that the risk of landslide excavation walls in excavation activities ranks highest in road work with a total RPN value of 460.8. Being hit and hit by heavy equipment during excavation activities is the highest risk in Geotextile Installation work, with a total RPN of 405.5, while in Precast Canal Installation work, The risk of being hit by a passing train when marking and staking out is the highest risk with RPN 344.1. Conclusion: the results of a review of HIRARC and JSA documents show there are 49 risks consisting of 14 risks in precast channel installation work, 19 risks in geotextile installation work, 16 risks in road bodywork
