三峡枢纽溢流坝段、坝体应力三维光弹性实验研究

本文应用三维光弹性实验方法,研究了三峡溢流坝在自重、水压力、泥沙压力等荷载作用下的结构应力状况,着重研究了新老混凝土的接缝对溢流坝坝体应力的影响。

Experimental Study on the 3-D Photoelasticity for the Dambody Stress in the Spillway Section of Three Gorges Project

Using the experimental method of 3-D photoelasticity, a study is made on the structure stresses of spillway dam in the project under the action of dead weight and load form pressure of water and sediment. Empha s is laid on the study of the effect of the fresh and old concrete bond on the dambody stresses.
