本文首先扼要地评述了这一课题国内外的研究情况,指出了关键问题在于至今还未弄清土压力的分布规律、大小及其影响因素,为此,对砂土填料的刚性挡土墙土压力进行了若干项目的试验研究。这些试验的试验设计及措施不同于过去同类的试验。通过试验,对土压力的非线性分布规律及影响因素有新的、重要的认识,这将有助于发展新的挡土墙土压力理论。
This article first briefly reviews the research situation at home and abroad, and points out that the key problem lies in the fact that the distribution law, size and influencing factors of earth pressure have not yet been ascertained. For this reason, the rigid retaining wall Stress Several pilot studies have been conducted. The experimental design and measures of these tests are different from those of the same kind in the past. Through experiments, new and important understanding of the nonlinear distribution rules and influencing factors of earth pressure will help to develop a new earth pressure theory of retaining wall.
