岩质边坡块体崩塌运动路径分析研究

The Analysis of Rock Slope Block Falling Movement Path

崩塌和落石是高陡边坡上经常发生的地质灾害现象.特别是在傍山建筑、道路边坡工程以及露天矿山边坡工程中,由于崩塌发生的突然而猛烈,对工程施工及人民生命财产造成巨大危害.同时,治理比较困难而且较为复杂,特别是对于大型崩塌,一般多遵循预防为主的原则.以岩质边坡滚石为研究对象,采用Rocfall数值模拟的方法,对滚石的运动特性、影响滚石运动轨迹的关键参数以及其确定、滚石灾害的防护等方面进行了系统探究.

Collapse and rock fall are geological hazards occur frequently on high and steep slope. It causes great damage to engineering construction and human life and property due to sudden and violent collapse, especially for buildings in mountain, cutting slope engineerings and open-pit mine slope engineerings. We mainly follow the principle of prevention first, for disaster governance is much more difficult and complicated, especially for large collapse consequences. Taking rock slope roiling stone as research object, we used the Rocfall numerical simulation method to study the movement characteristics of rolling stones, key parameter influencing rolling stones movement route and parameters determination and rolling stone disaster nrotection.
