The huge jetty project in West Kalimantan was found a sand soil with fine content that quite much about 35% up to 49%. According to USCS classification system, this soil is included to coarse-grained material. However, if this soil to be classified using AASHTO, this soil will include to fine-grained material. The initial judgement due to any fine content that quite much would close the pores in this soil and then excess pore water pressure could not be dissipated quickly as in the coarse-grained soils in general. Increasing excess pore water pressure that could not be dissipated quickly, there are any chance of settlement would be increase due to consolidation settlement occurred. And also undrained condition has to be considered in the calculation of bearing capacity of the foundation. In this thesis, the author conducted a study related to the evaluation of load transfer and settlement that occurred on the considered soil using finite element method of ABAQUS CAE. This software is used to this study because of its ability to model interaction of pile-soil is more satisfy in the along of pile and in the tip as well. And this software could model the respond of excess pore water pressure increase related to loading speed in the soil quite good. In order to ensure that model of the single pile is quite similar with in the field condition, the author conduct load-settlement curve matching between the model with the result of static loading test. The parameters from curve matching were then used for further analysis. Based on the results of the modeling and analysis, it was obtained that there was increasing of pore water pressure in considered soil that could not dissipated quickly. Then this condition cause additional long-term settlement of consolidation settlement and foundation capacity will obtain lower than the predicted since the considered soil was assumed as sand.
