摘要:为了更好的估计超固结比，本文阐明了将土的种类、土性指标和利用静力触探获得的前期估计压力与超固结比的经验公式联系起来。同时阐明了利用标准土工试验方法的重要性。通过搜集各种现场试验已发表或尚未发表的试验数据，得到标准的土的力学行为或应力历史与基于标准的土工试验方法获得的土的工程性质参数之间的经验公式，其中经验公式随着塑性指数、液性指数、中值粒径和有机质含量等参数的不同而不同。文中的案例被用来证明关系式应用的正确性。最后举了很多例子说明应用了本文提出的参数之间的相关关系。

Abstract：To enhance the assessment of the overconsolidation ratio (OCR), this paper describes the importance of relating the soil type and soil index properties to the empirical correlations used to evaluate the preconsolidation stress and OCR using the piezocone and the importance to the normalized soil behavior approach. Data from a variety of sites is assembled using published and unpublished sources to develop empirical correlations for the normalized soil behavior or the stress history and normalized soil engineering parameter-based approach that vary with the plasticity index, liquid limit, median particle size, and organic content of the soil. Examples are presented to illustrate application of the correlations.
