指数函数配合法分析整理孔压资料的探讨

By use of Exponential Function Assorting Method To Analyze and Sort Out the Pore Pressure Data

用孔压过程线反算固结系数是软土预压加固工程的主要分析工作。一般常米用的指数函数配合法须确定零点孔压,但实践中零点孔压难以准确确定。本文介绍的计算方法在计算时无须知道零点孔压,并可推算出零点孔压。

By use of pore-pressure process line to make inverse calculation for coef-ficent of consolidation is a main analytical work for consolidation enginee-ring, in which the soft soil is preloaded. In the usually used exponential function assorting method, it is necessary first to determine the zero point pore pressure. But in practicc,to determine the zero point pore pressure is a difficult work.The calculation method suggested in this paper needs not to know this value first, and it will he obtained later by calculation.
