关于水土压力计算及抗剪强度指标选用的探讨
摘要:抗剪强度指标是岩土计算中的重要参数，不同试验条件下的抗剪强度指标如何在工程实践中应用关乎工程的安全稳定与否，这一问题一直是工程界争论的热点。从基本概念入手，对一些似是而非的概念进行了梳理，提出了水土合算无实际工程意义，有效自重压力不能等同于有效应力的论断，概括了工程实践中如何选用抗剪强度指标的基本思路，期望能对正确理解土力学原理及工程实践有借鉴指导意义。
Abstract:The shear strength index is very important in geotechnical calculations,how to use the shear strength indices under different test conditions in engineering practice concerns whether the project is secure and stable,this problem has long been a rather hot debate in engineering rield.From the fundamentals,this paper elaborates some specious concepts,presents a thesis that calculating the water and the earth pressure together is insignificant in engineering,and the effective self-weight stress is not equal to the effective stress,meanwhile,it generalizes a basic idea that is how to choose the shear strength index in engineering practice Hope to have significance to accurately understand the theory of soil mechanics and direct engineering practice
