一、前言目前在确定地基的强度公式中,大体分为两大类:1.根据极限平衡的条件,以塑性区域开展的深度来确定作用地基上的压力的强度计算公式,属于这一类的公式有:马斯洛夫(Н.Н.Маслов)、布寿列夫断基、(Н.П.ПУзыревский)、莫罗佐夫、(П.и.морозв)等所谓的“安全强度”公式(即基础边缘未发生塑性区或刚开始发生塑性区),耶罗巴尔斯基(Яропольский)、谢梁宾 (Шоляпин)、莫罗佐夫等的塑性区开展至最大深度的所谓“临界荷重下的强度计算公式”以及其他作者的塑性区开展至与基础边线相切或开展至深度为基础宽度的1/3、1/4、1/2等时的强度公式(图1)。
I. INTRODUCTION At present, in the formula for determining the strength of foundations, they are roughly divided into two major categories: 1. Based on the conditions of limit equilibrium, the formula for calculating the strength of the pressure acting on the foundation is determined by the depth of the plastic zone, which belongs to this category. The formulas are: Maslov (Н.Н.Маслов), 布寿勒夫断基, (Н.П.ПУзыревский), Morozov, (П.и.морозв), the so-called “safety strength” formula (ie no plastic zone at the base edge or plastic zone at the beginning), the so-called “strength calculation under the critical load” of the plastic zone of Yaroslavsky (Яропольский), Xie Liangbin (Шоляпин), Morozov, etc. The formula " and the other author’s plastic zone are developed to the strength formula when tangent to the base edge or to a depth of 1/3, 1/4, 1/2, etc. (Fig. 1).
