摘　　要：大坝参数的推求是大坝观测资料分析的一个重要内容,本文以为这是依实际响应特性对大坝的理论模型修正的过程,其目的是使大坝的理论模型能反映在各种外载作用下的响应特性。本文在分布位移模型的基础上提出同时推求坝体和坝基弹模的方法,使大坝的有限元模型能反映在水压作用的整个坝体变形性质。In this paper, the evaluation of dam parameters is considered as a modification procedure of dam's theoritical model, on basis of the real dam response to external loads. The purpose of this evaluation is to ensure the theoritical model be able to describe the dam behaviour under the action of various loads. Based on the mathematical model of displacement distribution, a method useful to evaluate elastic modulus of dam body and its foundation is proposed, and a FEM model is formed, which can describe the displacement response of the dam under the action of water pressure.
