Analysis on Horizontal Bearing Capacity of Rectangular Pile Considering the Influence of Mud Skin——Based on Rama 3 to Bangkok West Outer Ring Expressway Project in Thailand
Based on the Rama 3 to Bangkok West Outer Ring Expressway project in Thailand,this paper first introduces the construction characteristics and natural geography of the project.Then,according to the application of rectangular piles in the project,the influence of mud skin generated during the pile formation process on the horizontal bearing capacity of rectangular piles is analyzed by ABAQUS finite element software.The results show that the rectangular pile has the characteristics of good horizontal bearing capacity and low construction cost compared with the circular pile.The existence of mud skin significantly reduces the bearing capacity of the rectangular pile.It is suggested to increase the post grouting after pile formation to improve the strength of the mud skin and prevent the insufficient bearing capacity caused by the insufficient strength of the mud skin.
