  • 摘要

    由于水库下压覆煤炭资源的开采,导致郓城城南水库大坝出现了不同程度的塌陷和变形,为了对水库大坝进行加固除险,文中首先分析了城南水库工程区域水文和工程地质,介绍了井下工作面的开采情况,确定了概率积分法的预计参数并进行了大坝开采移动变形预测。最后根据预测结果在考虑环境和水源水质影响的条件下制定了有针对性的大坝除险工程措施:对坝体进行加高加固,根据沉陷程度不同修建挡墙和齿墙,修建护坡和道路等。

  • Abstract
    Due to the exploitation of coal resources under the reservoir, the reservoir dam had collapsed and deformed to varying degrees, which posed a threat to the dam safety. Firstly, the hydrology and engineering geology were analyzed in Chengnan Reservoir project area, the mining situation was introduced on underground working face, the predicted parameters of probability integral method were determined, and the displacement and deformation of dam mining were predicted. Finally, ac cording to the forecasting results, under the condition of considering the influence of environment and water quality, a specific dam risk removal engineering measure w as formulated, the dam body was heightened and strengthened, and slope protection, retaining walls, toothed walls and roads were constructed according to different s ubsidence levels.
