基于沉降资料反演固结系数的方法研究
Back Analysis of Consolidation Coefficient with in-Situ Settlement Data
saoka法在岩土工程中成功用于工后沉降的预测，同时Asaoka方法中的 直线的斜率 和固结系数 的关系还被广泛用于反演地基的固结系数。但是相关资料表明用该方法反演得到固结系数与地基的固结系数存在一定的误差。本文分析了产生该误差的原因，并在该分析的基础上，根据Terzaghi一维固结理论从新推导了的 直线的斜率 和固结系数 之间的表达式。分析表明采用本文推导的 表达式反演的固结系数与地基的固结系数能够很好地吻合。
he Asaoka’s method has been successfully used to predict the post-construction settlement in geotechnical engineering practice. Based on the observed settlement data, the consolidation coefficient can be calculated with the quantitative expression of consolidation coefficient Cv versus the slopeβ1 of the Si~Si+1 line in the Asaoka’s method. However, it has been reported that the back-analyzed consolidation coefficients with the Asaoka’s method are not consistent with the in-situ one. The discrepancy was investigated in this study. A new expression for consolidation coefficient is proposed based on one-dimensional Terzaghi’s consolidation theory. The back-analyzed consolidation coefficients with the new way proposed in this study are quite consistent with the in-situ one.
