“应力史与归一化的土的工程性质参数”(缩写SHANSEP)法是美国麻省理工学院土木系Ladd教授与其合作者在七十年代初提出来的,并已成功地应用于美国东北部的麻省和缅因州以及南方密西西比河口等地的一些工程或研究项目中。近十余年来,这个方法在美国、英国、加拿大等国已被愈来愈多的人所接受和应用,但迄今仍以用于确定饱和软粘性土的原位强度为多。一、确定饱和粘性土强度和稳定性的φ)=0方法自从Skempton在四十年代末期提出稳定性分析的φ=0法及其理论基础以来,该法已成为美、英等国在分析饱和粘性土的稳定性中普遍采用的一种方法。此法假定在加 The “Strategy of Stress History and Normalized Soil Engineering Parameters” (SHANSEP for short) method was proposed by Professor Ladd of the Department of Civil Engineering at the Massachusetts Institute of Technology in the early 1970s, and has been successfully applied to the Northeastern United States. In some engineering or research projects in Massachusetts and Maine and the Mississippi Estuary in the South. For more than a decade, this method has been accepted and applied by more and more people in the United States, Britain, Canada and other countries, but it is still used to determine the in-situ strength of saturated soft cohesive soil. First, determine the strength and stability of saturated clay φ) = 0 method Since Skempton in the late forties proposed stability analysis of φ = 0 method and its theoretical basis, the law has become the United States, Britain and other countries in the analysis of saturation A method commonly used in the stability of clay soils. This method assumes that
