本文用空间有限元方法，通过计算成层上在旁压试验时土体中各点的应力与位移，对孔壁位移与孔壁压力的关系进行了分析，结果表明，在成层土中，旁压试验特征值几乎不受上石及下伏土层的影响，旁压试验成果不宜直接应用
In this paper, the spatial finite element method is used to calculate the stress and displacement of each point in the soil during the pressure test on the stratified layer. The relationship between the pore wall displacement and the pore wall pressure is analyzed. The results show that in the stratified soil, The characteristic value of the pressure test is hardly affected by the upper rock and the underlying soil layer. The results of the pressure test should not be applied directly.
