The foundation of Baise gravity dam has bad geological phenomena such as high elastic modulus ratio, joint fissures and large faults etc.

百色重力坝地质条件复杂，地基岩体具有高模量比、节理裂隙发育等不良地质现象。

It presents the method of "stiffness similarity", which has solved the design problem of model with difference of elastic modulus ratio in different parts between model and practicality.

提出了“刚度相似”的方法，有效地解决了模型与实型各部分结构弹性模量相似比不一致的模型设计问题。

We put the concrete flange plate of the composite beam into the steel ones according to the elastic modulus ratio and keep the width of section unchanged, as a result, get a equivalent section.

将组合梁中混凝土翼缘板厚度按弹性模量之比换算，并保持宽度不变形成等效截面。
