| 摘 要： | 本文通过对蓬安县三元水库大坝外坡裂缝产生的原因分析，进而运用岩、土力学的理论与方法反算推论出了裂缝的产生不是深层坝体土滑动引起的，而是局部浅层坝体土在水的诱发作用下作蠕滑-拉裂变形所产生的。在明确了大坝裂缝产生的原因后，提出了一系列相应整治工程措施，以达到彻底根治裂缝和稳固大坝的目的。

| Abstract: | After analysis of the cause of formation of cracks on outer slope of the Sanyuan Reservoir dam,reduction and dedution of physiscal parameters by using rock and soil mechanics theory and method,the author suggests that the cracks were formed by creep sliding deformation of local shallow dam-body earth under the influence of water instead of deep dam-body-earth sliding.Hence a series of corresponding crack treatment measures have been susggested for consolidating the cracks and stablizing the dam. |
