Abstract

One of the important parts in a building planning is foundation planning. The foundation is the lower structure of the building construction that is directly related to the ground and functions as a load-bearing building from above and will channel it into the ground. The existence of the foundation is not something that is not important, but has a big influence in the construction of the building to be built. The bore pile foundation is the foundation chosen for the Ngloram Airport construction project because it has several advantages such as the diameter and depth of the pile that can be changed as specified. The airport, which is located in the middle of the rice fields, has a type of clay soil, therefore the calculation of the magnitude of the load and the carrying capacity of the soil is very necessary in planning the foundation. The calculation of the carrying capacity is based on CPT data (cone penetration test) using 2 methods, namely Reese & Wright and O'neil & Reese. From the results of the analysis using the Reese & Wright method, Qijin was obtained at 483.1471 kN, while the results from O'neil & Reese obtained Qijin at 418.9704 kN. For the results of the calculation of the load calculated using the SAP 2000 application is 402.851 kN. So it can be concluded that the foundation is safe in holding the load on it.

Abstract

The foundation is an important part of building construction, acting as a support for the building and transferring loads evenly from the upper structure to the ground. In construction projects, one of the most important activities is to test the bearing capacity of bore piles using the Pile Driving Analyser (PDA) method. The purpose of this test is to ensure that the capacity of the bored pile can meet the structural requirements of the toll road, particularly in the face of significant vertical and lateral loads. Improving the efficiency of the PDA (Pile Driving Analyzer) testing method is an important challenge in the foundation of bored piles in infrastructure projects. This study discusses the analysis of the use of the Frame Portal PDA as an alternative to the crane hammer method. The analysis includes quality, time and cost aspects on the Toll project. The results show that the PDA Portal Frame method is more efficient with a cost saving of Rp109,010,524.00 and a reduction in implementation time for 2 days of test points compared to the crane method. In addition, the PDA Portal Frame structure has a maximum deformation of 0.030 mm, which is within safe limits according to SNI 2847-2019.

Abstract

Soft soil is characterized by low bearing capacity, high compressibility, and substantial settlement, thereby frequently causing complications in road embankment construction. One viable method for soil improvement is stabilization utilizing eco-friendly materials, such as bamboo chips. However, research concerning the effects of varying bamboo chip mixtures on the stability and settlement of embankments constructed on soft soil remains limited. This study aims to analyze the impact of bamboo chip mixture variations on consolidation characteristics, embankment stability, and soft soil settlement, utilizing the finite element method via PLAXIS 2D software. The investigation was conducted through one-dimensional consolidation testing (oedometer tests) on native soil and bamboo chip mixture variations of 25%, 30%, and 35%. The experimental results served as input parameters for the PLAXIS 2D numerical modeling to evaluate the safety factor and embankment settlement. The findings indicate that the incorporation of bamboo chips effectively enhances embankment stability and mitigates soil settlement compared to untreated soil conditions. The TA + BC (Native Soil + Bamboo Chips) 30% variation yielded the most optimal outcomes, exhibiting the lowest compression index and consolidation settlement, alongside a higher safety factor relative to the other variations. Overall, bamboo chips demonstrate significant potential as an economical and environmentally sustainable alternative stabilization material for road embankment construction over soft soils.
