地基压缩层厚度可视作基础沉降量的函数,其计算方法一般如下:设p_0=基底附加压力,则基底下p_0=0.2γ(D+z)深处为地基压缩层底部界线(式中D为基底埋深,Z为地基压缩层厚度,γ为地基土容重),故需绘制附加压力曲线与地基自重压力曲线才可求得,求法颇为麻烦。笔者为简化求法,特绘制以下的求地基压缩层厚度的组合曲线组,可在图上简捷求出,提高工效,满足勘察设计要求。
The thickness of the compressive layer of the foundation can be regarded as a function of the foundation settlement. The calculation method is generally as follows: Let p_0 = substrate additional pressure, then the depth of p_0 = 0.2γ (D + z) below the base is the bottom boundary of the foundation compression layer ( For the depth of the basement, Z is the thickness of the compressive layer of the foundation, and γ is the bulk density of the foundation soil. Therefore, it is necessary to plot the additional pressure curve and the pressure curve of the foundation’s own weight to obtain it. In order to simplify the method, the author draws the following combination curve group for finding the thickness of the compression layer of the foundation, which can be obtained simply and conveniently on the map to improve the ergonomics and meet the survey and design requirements.
