有效应力原理的英文表述
English:
"The principle of effective stress, also known as the principle of effective tension or Terzaghi's principle, is a fundamental concept in geotechnical engineering and soil mechanics. It states that the total stress on a soil mass consists of two components: the effective stress and the pore water pressure. The effective stress is the intergranular stress transmitted between solid particles in the soil skeleton, while the pore water pressure is the pressure exerted by the water filling the void spaces between soil particles. According to this principle, the strength and deformation behavior of soils are primarily controlled by the effective stress, rather than the total stress. This concept is crucial in various geotechnical applications, including slope stability analysis, foundation design, and earth pressure calculations. Understanding the effective stress principle is essential for accurately predicting the behavior of soil under different loading conditions and ensuring the stability and safety of engineering structures."
中文翻译:
“有效应力原理，又称有效张力原理或泰尔扎基原理，是岩土工程和土力学中的基本概念。

它表明土体的总应力由两个组成部分组成：有效应力和孔隙水压力。

有效应力是土体骨架中固体颗粒之间传递的颗粒间应力，而孔隙水压力是由填充在土粒之间空隙中的水所施加的压力。

根据这个原理，土壤的强度和变形行为主要受到有效应力的控制，而不是总应力。

这个概念在各种岩土工程应用中至关重要，包括边坡稳定分析、基础设计和土压力计算。

理解有效应力原理对准确预测不同加载条件下土壤的行为，确保工程结构的稳定性和安全性至关重要。
