摘要: 在对泥石流沟进行详细的地质勘察的基础上,对北京市密云县前火石岭泥石流灾害设计浆砌石拦挡坝进行治理,并对拦挡坝进行了稳定性计算,得到了坝体相关参数及3种设计工况下的抗滑稳定系数、抗倾覆稳定性和地基稳定性。该方案的设计实施,将有效削弱泥石流的致灾能力,降低泥石流对前火石岭村村民生命财产及村内公共设施的威胁,对于维护社会与生态环境的稳定具有积极意义。Abstract: Based on the detailed geological investigation of the debris flow gully in Qianhuoshiling village, the stone land-slide masonry dam for the debris flow control was designed;the stability of dam was calculated to learn the related parame-ters, the anti-slide stability coefficients and anti-overturning stability&foundation stability under three kinds of design con-dition.By the design and implementation of the program, the influence of the debris flow could be effectively weakened to protect the safety of life and property of the villagers.
