摘要

在软土工程中，地基土的固结系数是重要参数。目前固结系数的选取主要根据室内固结试验得到的沉降与时间曲线得到。但已有的研究成果表明，室内试验获得的固结系数远低于现场资料反演得到的固结系数，取样扰动是一个重要的影响因素。根据Hong & Onitsuka的扰动度定义，推导了取样扰动对固结系数的影响，并引用了大量的试样数据验证了分析的合理性。

Abstract

The consolidation coefficient is key parameters in the soft clay engineering. At persent

the consolidation coefficient is obtained mainly by the lab oedometer and back analysis with in-situ observed settlements. But the lab coefficient is much less than that from back analysis of in-situ data. The sample disturbance is an important factor. The coefficient after disturbance is achieved with the disturbance degree proposed by Hong & Onitsuka; After validation by former research

the coefficient is discussed.
