摘要
通过对江苏地区电场项目9根嵌岩灌注桩竖向静载试验结果研究,讨论了江苏土岩组合地基中嵌岩桩竖向承载力与位移关系,以及试验加载与桩周土侧阻力、嵌岩段阻力关系。按照不同规范推荐的岩石端阻力与岩石饱和单轴抗压强度f_(rk)关系,探讨了试验结果f_(rk)取值问题,并给出设计建议,从而为实际工程设计提供参考。
By studying the results of the vertical static load test of 9 rock-socketed cast-in-place piles in the electric field project in Jiangsu area,the relationship between the vertical bearing capacity and displacement of the rock-socketed piles in the soil-rock composite foundation in Jiangsu is discussed,as well as the relationship between the test loading and the lateral resistance of the pile surrounding the rock resistance relationship.According to the relationship between the resistance of the rock and the saturated uniaxial compressive strength of the rock recommended by different codes,the value of the test result of f_(rk)is discussed,and design suggestions are given,so as to provide a reference for the actual engineering design.
