摘要

由于边坡岩体本身的非均质性和赋存环境的复杂性，以及边坡岩体的力学特性参数及赋存环境总是处在动态的演化过程之中，因此，决定参数取值是数值计算中的一个难点，它直接关系到计算成果的准确性与可靠性。在材料参数反演分析的基础上，对三峡永久船闸边坡的开挖效应进行了分析，并进一步分析了三峡船闸的应力变形状态，旨在对船闸运行期的变形稳定分析提供依据。

Abstract

Parameter evaluation is one of key problems in numeric analysis considering non-homogeneous rockmass and complex surroundings as well as dynamic mechanic features of slope rockmass. Its accuracy has direct influence on accuracy and credibility of computational result. On the basis of parameter back analysis

excavation effect of permanent shiplock high slope of Three Gorges Project and further stress-strain state are analyzed. It provides foundation for deformation and stability analysis of operation stage of permanent ship lock.
