Analisa Perbandingan Daya Dukung Hasil Loading Test pada Bore Pile Diameter Satu Meter Tunggal dengan Metode Elemen hingga Memakai Model Tanah Mohr Coulomb pada Proyek Crystal Square Medan

Abstract

strong and solid foundation is needed in every building since as a foundation of a building must be able to support the whole body of the building and the other burden until the layer of the soil. Loading test is usually performed in order to know the support capacity of the pile foundation, and the implementation costs a lot of money, so in the case of the 319 existing pile, three pile only done loading test. The aim of the thesis was to analyze the amount of the support capacity of the bore pile foundation axial of a single meter in diameter by using the data from the soil investigation in the field and the data from the laboratory and compared them by using the Finite Element method by using Plaxis program. The whole result was compared with the result of the loading test performed in the field The Element method has been used to know the soil characteristic as the model. The aim of the thesis was also to analyze and to predict the support capacity of the other bore piles without the loading test in the same project so that it does not need to perform the loading test any more for economic reason. There was 868 tons of value disparity of the result of the support capacity calculation in the ultimate foundation, based on the result of the soil investigation in the field The result of the Finite Element which was consolidated, according to ASTM was 730 tons, the result of the Finite Element model which consolidated in seven days was 63 0 tons, and if it was compared with the result of the loading test in the field, it was 791.5 tons. The lowering of the Finite Element model which was consolidated, according to ASTM at the biggest load (830 tons) was 24.81 mm, and the lowering of the Finite Element model which was consolidated in seven days at the biggest load (830 tons) was 24.95 mm. If it was compared with the result of the loading testing the field, the lowering at the biggest load (830 tons) was 24. 72 mm, while the lowering according to ASTM Dll43/81 was one inch (25.4 mm); this indicated that the vertical load test hadfulfilled the requirement of ASTM DJ 143/81.
