目前很多地方公路部门对涵洞和管道顶以上填土高度和涵洞与管道土压力计算问题重视不够,导致大量拱涵、管道出现开裂。从已有的研究成果和国内外文献资料出发,本文介绍国内外高填上埋式结构垂直土压力理论,结合模型实验,指出目前高填上埋式结构垂直土压力理论的不足,总结了一些有价值的规律性成果,对于指导工程实践有一定的参考意义。
At present, many local highway departments pay insufficient attention to the calculation of the filling height of culverts and culverts and the calculation of culverts and pipe earth pressures, resulting in a large number of arch culverts and pipelines cracking. Based on the existing research results and literature both at home and abroad, this paper introduces the theory of vertical earth pressure of buried structures with high filling at home and abroad. Combining with the model experiments, the author points out the deficiencies of vertical earth pressure theory of buried structures with high filling at present, Valuable regularity results have certain reference meaning for guiding engineering practice.
