Profiling Stress History of Clays Using Dual Piezocones

拟议的研究将包括综合 从以前的努力中汇编的可用压电锥数据， 收集额外的现场和实验室数据，以及 制定一种基于理论的方法， 压电锥参数的互补组，以描绘 天然粘土的原地应力历史。数据库 汇编将用于校准和指导 选择适用的压电锥参数， 超固结比的详细分析，或其他 应力历史的相关测量。

The proposed research will include the synthesis of available piezocone data compiled from previous efforts, the collection of additional field and laboratory data, and development of a theoretically-based methodology for using complementary sets of piezocone parameters to profile the in situ stress history of natural clays. The database compilation will be used to calibrate and guide the selection of applicable piezocone parameters for the detailed profiling of overconsolidation ratio, or other relevant measure of stress history.
