Abstract

AbstractSome buildings impose limits on the foundation displacement that occur with relatively small values so as not to cause structural damage. The test method used was to make a model test box as a testing medium by simulating the actual model into the form of a scale model. The study was conducted using a single pile foundation with reduced scale, made of concrete with a diameter of 0.02 m, 0.03 m, 0.04 m and the length of each pile was 0.4 m. The pile model was mounted by pressing into the clay that had been compacted in the test box and then given a tensile load which refers to ASTM D3689-07 procedure E (Constant Rate of Uplift Test). Mobilization of pile friction resistance at critical displacement determined the frictional resistance of the ultimate pile units. The test results showed that the greater the diameter of the pile, the frictional resistance of the ultimate pile units would increase. The increase in frictional resistance of the ultimate pile units showed an average value of around 17.1%.Keywords : Pile foundation, Pile diameter, Friction resistance.AbstrakMeningkatnya pembangunan hunian mengakibatkan naiknya permintaan akan batako, hal ini tentunya Beberapa konstruksi bangunan memberikan batasan kepada perpindahan tiang yang terjadi dengan nilai yang relatif kecil supaya tidak menyebabkan kerusakan struktur.

Abstract

In a bridge construction project, there are two types of structures, namely the superstructure and the substructure. The foundation is part of the substructure that functions as the main support and the most important part that greatly affects the stability of the building above it. In foundation design, it is required to calculate the bearing capacity. The bearing capacity of the foundation can be predicted based on soil investigation data which compared by actual field dynamic test data. Dynamic test is carried out to determine the actual bearing capacity after pile installation. This research aims to predict of spun pile bearing capacity and settlement based on N-SPT data, then evaluated by dynamic test (PDA and calendering) at “X” Toll Road Construction Project. Moreover, an evaluation of the axial bearing capacity of single and group piles will be carried out against the workloads. The results shows that prediction of the bearing capacity closest to the PDA data using Luciano Decourt Method (1987) around 309.45 tons with a difference of 4.20% each other. Calendering analysis by Gates Method found that 301.46 tons with a difference of 50.8% against the prediction. The prediction of immediate settlement is obtained of 26.79 mm smaller than PDA result and a difference of 13.30%. The results of the evaluation of the axial bearing capacity of single and group piles against workloads show that both the predicted and actual (PDA and calendering) bearing capacity is greater than the workload.

Abstract

Abstract Shaft resistance of tension pile will be fully mobilized at certain displacement. Some structures impose limits to the displacement of pile with a relatively small value in order not to cause damage. Therefore, it is necessary to know the behavior of pile resistance reaction against load that works in every displacement. The study was conducted using the model of single pile made of concrete with a length of 0,2 m ; 0,3 m ; 0,4 m and each diameter 0,02 m ; 0,03 m ; 0,04 m. The model pile is jacked in sand that has been compacted in a box and then given uplift load that refers to the ASTM D3689-07 procedure E. Pile resistance reaction is shown by pile friction modulus and determined by mobilized unit shaft resistance and pile displacement relationship. The results showed that mobilization of uplift resistance of mini pile that has been counted using friction modulus can only approach the value of true observations, so that it requires further consideration as design parameter. Keywords : Mini pile, sand , uplift resistance.

Abstract

ABSTRACT Some buildings imposes limits to pile foundation displacement with relatively small value so as not to cause damage to the structure. Loading test directly in the field requires a very high cost. To overcome this problem, it can be approached with a more economical cost, that is to move it into a certain scale models. The method used is to create a media model as a test box testing, by simulating the actual model in the form of a scale model. This method is fairly cheap and efficient as it can be used for various models and can be used repeatedly. The study was conducted using models of reduced scale single pile foundation made of concrete with a length of 0.2 m, 0.3 m, 0.4 m and each diameter of 0.02 m, 0.03 m, 0.04 m. Pile model is jacked in clay soil that has been compacted in a box and then given a tensile load test referring to ASTM D3689-07 procedure E (Constant Rate of Uplift Test). Mobilization of frictional resistance is determined from the pile frictional resistance force and displacement of the pile. The results showed that the frictional resistance value is reduced to the value at a particular displacement or at critical displacement pile. Keywords : scaled pile foundation , test box , small displacement , clay ABSTRAK Beberapa konstruksi bangunan memberikan batasan kepada perpindahan tiang yang terjadi dengan nilai relatif kecil agar tidak menyebabkan kerusakan struktur. Uji pembebanan langsung di lapangan memerlukan biaya yang sangat tinggi. Untuk mengatasi masalah ini maka dapat dilakukan pendekatan dengan biaya yang lebih ekonomis yaitu dengan memindahkan media lapangan ke media laboratorium dengan skala model tertentu. Metode yang dipakai adalah membuat box uji model sebagai media pengujian, dengan mensimulasikan model yang sebenarnya ke dalam bentuk model skala. Metode ini cukup murah dan efisien karena dapat dipergunakan untuk berbagai model dan dapat dipergunakan secara berulang. Penelitian dilakukan menggunakan model fondasi tiang tunggal skala tereduksi yang terbuat dari beton dengan panjang 0,2 m, 0,3 m, 0,4 m dan masing-masing diameter 0,02 m, 0,03 m, 0,04 m. Model tiang dipasang dengan cara ditekan pada tanah lempung yang sudah dipadatkan dalam box uji kemudian diberikan beban tarik yang mengacu pada ASTM D3689-07 prosedur E (Constant Rate of Uplift Test). Mobilisasi tahanan gesek tiang ditentukan dari tahanan gesek satuan dan perpindahan tiang. Hasil penelitian menunjukkan bahwa nilai tahanan gesek berkurang pada nilai perpindahan tiang tertentu atau pada perpindahan tiang kritis. Kata kunci : model pondasi, box uji, perpindahan kecil, lempung

Model tiang dipasang dengan cara ditekan pada tanah pasir yang sudah dipadatkan dalam box uji kemudian diberikan beban tarik yang mengacu pada ASTM D3689-07 prosedur E (Constant Rate of Uplift Test). Tahanan tarik tiang ditentukan tahanan gesek satuan dan perpindahan tiang berdasarkan variasi pengaruh diameter dan panjang tiang. Hasil penelitian menunjukkan bahwa nilai tahanan gesek satuan ultimit (fs) dan perpindahan kritis (δc) relatif menurun dengan bertambahnya ukuran diameter (d) tiang tetapi sebaliknya nilai fs tiang meningkat dengan dengan bertambahnya ukuran panjang (L) tiang. Semakin besar panjang tiang memperlihatkan kecenderungan bahwa pengaruh tekanan tanah lateral pasir terhadap selimut tiang meningkat sehingga memberikan kontribusi tahanan gesek yang lebih besar, sedangkan penambahan diameter tiang tidak meningkatkan tekanan tanah lateral pasir terhadap tiang.Katakunci : Tahanan tarik, pasir, Model Fondasi tiang.
