Profiling Stress History of Clays Using Dual Piezocones

这项拟议的研究将包括综合先前工作汇编的现有压电锥数据，收集更多的现场和实验室数据，并开发一种基于理论的方法，使用互补的压电锥参数集来描绘天然粘土的地应力历史。数据库汇编将用于校准和指导选择适用的压电锥参数，以详细描述超固结比或其他有关应力历史的测量方法。

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.
