| 摘 要： | 对边坡稳定性进行评价和预测是整个边坡工程的关键.以矢量和可靠性计算为手段建立了块状结构岩体数学模型,分别运用确定性和不确定方法对块状结构岩体进行稳定性分析,为岩质边坡稳定性评价提供了新的途径.利用所建模型分析了三峡工程永久船闸边坡关键块体的稳定概率.结果表明,边坡中可动快体失稳概率较大,需采取相应的加固措施.工程实践证明,所建模型的实用性较强、应用前景广阔.

| Abstract: | A reliability model for blocky rockmass stability is made by means of block theory and hemispheric projection.This is a new direction for stability evaluation.As a typical example,this means has been applied to stability analysis of key block at shiplock high slope in Three-Gorges project ,the far hydropower station project in the world.The applying prospects and adaptation of the model are shown by project example. |
