1 前言 粘性土地基承载力的确定方法较多,目前常用的方法有三种:理论公式计算法;根据地基土的性质指标查《建筑地基基础设计规范》(GBJ7—89)(以下简称《规范》)的承载力表计算方法;现场载荷试验和动力触探试验方法。 《规范》编制的地基承载力表可分为两类:一类是根据地基土的物理力学指标从表中查得承载力基本值f_o,再经过修正得出承载力标准值f_k;另一类是根据标准贯入击数N的修正与统计值,从表中直接查得承载力标准值f_ko在《规范》中,后一类方法只是提供了一些离散的点,而这些离散点呈非线
1 Preface There are many ways to determine the bearing capacity of cohesive soil foundation, there are three commonly used methods: theoretical formula calculation method; based on the nature of foundation soil found in the “Code for Design of Foundation of Building Foundation” (GBJ7-89) (hereinafter referred to as “Code” ) Bearing capacity table calculation method; field load test and dynamic penetration test method. The “foundation” of the foundation bearing capacity table can be divided into two categories: one is based on the physical and mechanical indicators of soil found in the table from the table bearing capacity of the basic value f_o, and then revised to obtain the bearing capacity standard value f_k; the other Is based on the standard penetration through the number of amendments and statistical N, directly from the table to check the standard value of bearing capacity f_ko In the “standard”, the latter method only provides some discrete points, and these discrete points are non-linear
