Abstract

Beach damage is a serious problem which requires prompt action from the government. Adding more sediment to the beach (beach nourishment) is one of the efforts to cope with the problem. However, the sediment filled is usually carried away by the wave, which consequently brings maintenance costs for dealing with the sandpile during certain periods, as well as the need for large volume of excavation. One of the alternatives to reduce the loss of the sediment pile is by constructing off-shore submerged structure with the crest of the structure is set submerged and made from geotube. The objective of this study was to identify the influence of wave steepness to the beach profile formed behind the structure. The physical model test was carried out to the sand of Tanjung Ann beach (d50=1.47 mm) under two conditions: without the submerged structure and with the geotube submerged structure within wave period (1; 1.2; 1.4; 1.6; and 1.8 second), wave height (6,7,8,9,10,12,14, and 16 cm). The laboratory scale (small scale) was used. Model was placed in the wave channel with initial profile slope of 1:6 and was subject to constant regular wave until the beach profile balance was achieved. Results of this study showed that the beach profile slope was formed behind the geotube submerged structure and grouped into two zones: the swash zone and the breaking zone. The swash zone was where the highest run up and the lowest run down occurred and the breaking zone is where the Dean’s formula applied. The influence of wave steepness (increasing Ho/Lo) was the increasing setback of the beach profile behind the geotube submerged structure. It would give benefit when the H0/L0 ≤ 0.068 for constant structure height.

Abstract

Bearing capacity of pile foundation bearing capacity is influenced by several factors, such as the amount of applied loads and non-homogeneous soil characteristics. To determine the bearing capacity of single pile foundation the static method is used on the basis of CPT data and dynamic methods based on dynamic pile and PDA tests. Pile foundations of the Pelawa bridge used in this study are located in the District of Parigi - Moutong. The study of literatures and secondary data such as the data of driven pile equipment, driven piles , CPT, dynamic pile tests, and PDA tests are used for analyzing the pile bearing capacity . Meyerhof method, Aoki de Alencar, LCPC, Price and Waldre, and Schmertmann are used to determine the bearing capacity of pile based on sondir (CPT) data. The dynamic pile tests data are used to calculate the bearing capacity of the piles by using methods of Hiley, Olsen and Flaate , Enginering News Record (ENR) , Janbu Mansur and Hunter , and AASHTO . The results show that  the lowest dan the highest of the ultimate bearing capacities  for static methods (CPT data) are  114.096 tons (Aoki De Alencar) and 305.479 tons (Schmertmann) respectively. Kalendering method (dynamic pile data) show that the lowest value of 284.22 tons were obtained from equation given by Hiley and the highest 1450.26 tons were obtained from equation given by  Janbu.The range of 171.2 tons - 174.5 tons were given for PDA test data. The ratio between CPT to PDAs results that are closest to the value of 1 which is 0.938 is the value that obtained from Meyerhof’s equation, while the ratio between dynamic method (kalendering) to PDAs results that are closest to the value of 1 which is 1,660 is the value that obtained from Hiley equation Keywords: single pile bearing capacity, CPT, dynamic pile test, PDA test

Abstract

Hubungan dari perilaku fisik dan mekanis pada jenis tanah bercampuran butiran halus belumlah tepat  jika hanya mengindikasikan penggunaan nilai angka pori (e) saja, maka penggunaan angka pori interfine disarankan untuk kondisi pasir bercampur butiran halus dengan jumlah butiran halus di atas ambang batas kandungan butiran halus (FC > FCth). Untuk mengetahui sifat fisik dan mekanik, letak nilai ambang batas kandungan butiran halus (FCth) serta hubungan antara angka pori interfine dan kuat geser terhadap  campuran pasir Siuri dan butiran halusnya, dilakukan pengujian di laboratorium dengan mencampur butiran  kasar dan butiran halus  pasir Siuri dengan jumlah butiran halus nonplastis yang bervariasi, mulai dari 0% sampai 100% terhadap berat campuran. Hasil penelitian menunjukkan bahwa nilai ambang batas kandungan butiran halus (FCth) berada di antara 30%-40% penambahan butiran halus. Untuk hubungan  sifat fisik dan mekanik dari campuran pasir dengan butiran halus ini,  nilai berat isi akan meningkat sedangkan nilai angka pori mengalami penurunan sampai pada ambang batas kandungan butiran halus (FCth), selanjutnya kondisi sebaliknya akan terjadi setelah melewati nilai (FCth) tersebut. Untuk hubungan angka pori interfine (ef) dengan Kuat geser (t)  menunjukkan bahwa dengan penambahan butiran halus nonplastis di atas ambang batas kandungan butiran halus (FCth ≥30%), akan menyebabkan penurunan nilai angka pori interfine (ef). Sedangkan untuk nilai tegangan gesernya juga mengalami penurunan seiring menurunnya nilai angka pori interfine (ef). Kata kunci : Pasir Siuri, kuat geser, angka pori interfine (ef), kadar butiran halus

Abstract

Tawaeli - Toboli is one of road that oftentimes undergo landslide. Most of these roads are in a mountainous area with steep slope angles . The road conditions worsened, especially the citizen do not know anywhere that is prone to landslides. The purpose of this study was to analyze slope stability using bioengineering methods. This method is used to increase the strength of the soil, and stabilize slopes and reduce erosion on slopes .The primary data for this study were obtained by conducting laboratory tests, including testing of bulk density, moisture content, density and shear testing directly without the influence of vegetation roots and the influence of vegetation roots to get the cohesion (c) and friction angle (ϕ ). Data field conditions include high slope and vegetation types. Analysis of slope stability calculated using the Slope / W. Calculation of earth pressure is calculated using the Rankine and Coulomb theories and calculations of stability against the collapse of the soil bearing capacity is calculated based on the equation Hansen and Vesic .From the results of the analysis showed that the presence of plant roots can increase the value of the cohesion and friction angle of the soil that can contribute to an increased safety factor of slope stability. Slope stability analysis using program Slope/W at the root of the condition without having the stability of the landslide is smaller compared with the conditions of using the roots , the results of the calculation of the shear strength of the soil without roots is smaller than the roots and results of calculations using the stability of the retaining wall retaining wall with the same dimensions at which point I Km 17 ± 300, the cantilever type retaining walls with roots influences security ineligible dimensional slope stability due to the retaining wall is not in accordance with the conditions of soil containing the roots of plants. Increasing the value of cohesion and angle of friction on the ground with roots influences can maintain the stability of the slope. Keywords: retaining walls, bioengineering, landslide
