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.

拟议的研究将包括综合以前的工作中汇编的可用压电锥数据，收集额外的现场和实验室数据，以及开发基于理论的方法，使用一组互补的压电锥参数来描绘天然粘土的原位应力历史。数据库编译将用于校准和指导选择适用的压电锥参数，以进行超固结比的详细分析，或应力历史的其他相关测量。
