| 摘 要： | 天生桥一级面板堆石坝建成投入运行后不久，位于河床中间的面板发生横河向挤压破损，接近坝顶部位的面板破损程度比水下部位严重。通过对大坝面板应变、应力分布规律的观测，并应用强度理论对面板破损原因进行的分析，表明面板破损状况与所在部位的应力状态有关，这为面板的修复提供了依据。

| Abstract: | The face slabs of the dam in the middle were crushed and destroyed after it was put into operation soon.The slabs near to the crest are damaged more serious than those slabs under the water.This paper analyzes the distributed regularity of stresses and strains of face slabs of Tianshengqiao cascade-I dam and the strength theory is applied to interpret the damage causes and damage patterns.The analysis showed that the damage situation is related with the stresses at that area.It provides the evidence for permanent repair of the damaged face slab. |
