一、前言土工参数反分析是指利用实测数据,选择恰当的岩土模型,通过各种数学分析手段反算土工参数,从而指导工程实施和验证现有的一些理论。近来,反分析无论在室内试验或现场试验方面都取得了令人信服的结果,已日渐成为广泛接受的验证理论和估算土工参数 I. INTRODUCTION The back analysis of geotechnical parameters refers to the use of measured data, selection of appropriate geotechnical models, and backcalculation of geotechnical parameters through various mathematical analysis methods to guide the implementation and verification of existing theories. Recently, the reverse analysis has achieved convincing results both in laboratory tests and field tests, and has gradually become a widely accepted verification theory and estimation of geotechnical parameters.
