摘要： <正>通过对饱和土和非饱和土的有效应力原理的对比分析 ,以及非饱和土的土颗粒模型研究 ,总结了非饱和土的Bishop有效应力公式在理论上和应用上的不足。提出应当分别考虑外加应力和吸力对土样变形与强度的影响 ,推导出非饱和土的广义有效应力原理 ,并提出试验验证的基本思想。
Abstract: The difference on effective stress principle between saturated and unsaturated soils is analyzed.A study on the particle model of unsaturated soil is performed.The limitation of Bishop effective stress formula for unsaturated soil in theory and application is summarized.The influence on deformation and strength by force and suction should be considered respectively.Then the generalized effective stress principle for unsaturated soil is deduced.The validating test method is put forward.
