岩土类材料的静水压力效应研究

Study on hydrostatic pressure effect of geotechnical materials

岩土材料的抗剪强度主要包括黏聚强度和摩擦强度,受静水压力的作用较为明显,同时对材料的基本物理性能产生很大的影响。本文基于前人研究的角度对两种静水压力对岩土材料的强度影响进行了分析,并总结了抗剪强度的影响规律,研究表明在低静水压力下岩土材料的剪应力破坏较为严重,而高静水压力作用下岩土材料表现为剪应力破坏,希望为我国的岩土工程的建设和岩土材料研究提供必备的理论支持。

The shear strength of geo materials mainly includes cohesive strength and friction strength, and the effect of hydrostatic pressure is more obvious. Meanwhile, it has a great influence on the basic physical properties of geo materials. In this paper, previous research based on the perspective of two kinds of hydrostatic pressure on rock and soil material strength are analyzed, and summarized the influence of shear strength, the study showed that in the low hydrostatic pressure of rock and soil material shear stress damage is more serious, and the high hydrostatic pressure of rock and soil materials for shear stress hope to provide the necessary support, for the study of the theory construction and geotechnical materials in geotechnical engineering in China.
