混凝土坝空间位移场的确定性模型反演分析法

Concrete Dam's Inversion Analytical Procedure with the Determinary Model of Space Displacement Field

提出用空间位移场的确定性模型，反演混凝土坝坝体的弹性模量，以及坝基和库区的变形模量，用多测点的原泣观测资料，真实地推求影响坝体运行的重要参数，并用于评判大坝的工作性态、反馈设计和施工。该方法用于某重力拱坝，得到的结果令人满意。

his paper advances a method that,with the determinary model of spece displacement field,inverses the elastic modulus of concrete dam,as well as the deformation modulus of the foundation of dam and reservoir region.It uses in situ observed data of several observation points to derive actually the important parameters which affect the oporation of the dam and that can be applied to evaluate the running characteristics of dam and feed back to design and construction. This inverse procedure has also been applied to some gravity arch dam,the result is satifactory.
