摘要
Abstract
Combined with the engineering geological data of Nanning Liujing transportation station in Guangxi, the influence factors of the lateral resistance of the pile embedded in the karst area were studied in this paper. Con⁃sidering rock⁃socketed depth, sediment thickness and mudcake thickness as influencing factors, the representative combinations were selected according to the orthogonal design method, and the numerical analysis of pile side resis⁃tance was carried out by the finite element software ANSYS. Range method was employed to study the influence of different factors on the pile side resistance accounted for the extent of the impact of the proportion of load. By the numerical simulation results, it can be seen that the influence of rock⁃socketed depth is the greatest, the next is the thickness of the sediment, and the influence of the mudcake thickness is the least. Based on the various influencing factors of rock⁃socketed pile side resistance, it has a certain reference value for the design of pile foundation in karst area.关键词
