本文首先对国内外的研究现状作了回顾和总结，然后主要针对土工织物加筋粉煤灰复合体的本构关系和计算理论进行研究，主要内容有： （ 1 ）将土工织物和周围土体视为一种近似的弹性非线性横观各向同性体，研究它的应力应变关系，充分考虑它的各向异性，得到土工织物加筋粉煤灰复合体的本构模型，然后通过大量室内试验进行分析验证； （ 2 ）引入有关渗流理论，即柯兹尼-卡尔曼（ kozeny - carman ）经验公式，将渗透系数引进到土体本构关系中。 - Macroscale inversion analysis of measured displacements in tunnel , slope and dam is studied detailedly according to inverse formulation method and direct formulation method . aimed at inverse problem for identifying original geostress parameters and stru - ture modulus of rock , linear hypothesis for shear stress field of slope is proposed . structural model of transversely isotropic medium is constructed
针对逆源(初始地应力)和逆介质(岩层结构模量)的识别问题，提出了地层剪应力场的线性假定，构造了横观各向同性体的结构性计算模型，应用了逆定式化有限元反演方法，快速地搜索到了被识别参数的最优值。
