目前,我国确定基础下地基压缩层深度的计算方法,主要是根据我国现行规范TJ7-74所规定的方法(下称规范法)。规范法比过去所用的附加应力与自重应力比值法来得合理,但也存在着一定的缺陷。主要为:1.压缩层深度及沉降量存在“极限值”(详
At present, the calculation method for determining the depth of compression layer under foundations in China is mainly based on the method specified in the current Chinese specification TJ7-74 (hereinafter referred to as the “standard method”). The normative method is more reasonable than the additional stress and self-weight stress ratio method used in the past, but there are also certain defects. Mainly: 1. There is a “limit value” for the depth of the compression layer and the amount of settlement (Details
