Abstract

A numerical method is developed for calculating a pile foundation of bridge support with karst deformations forming in the base, taking into account the formation of ‘negative’ friction on the lateral surface of the piles. The bearing capacity, settlement, and stiffness coefficients of the piles are obtained as functions of the foundation geometry, pile load, settlement prior to karst deformation, distance to the roof of the rocky karst soils, and calculated cavity diameter.

将岩溶变形考虑在内的桥梁支撑桩基计算

考虑到桩侧表面 "负 "摩擦力的形成，开发了一种数值方法，用于计算基底发生岩溶变形的桥梁支座桩基。根据地基的几何形状、桩荷载、岩溶变形前的沉降、到岩溶土壤顶面的距离以及计算的空洞直径，得出了桩的承载力、沉降和刚度系数。
