| 摘 要： | 某特大桥西侧桥头边坡为顺层岩坡,受桥墩加载及下游某水库蓄水影响,岸坡存在安全隐患.在工程地质调查的基础上.查明了岸坡赋存的水文、工程地质条件,建立了地质模型,明确了岸坡稳定性控制因素;针对控制性结构面及岩体,开展细致研究,获取了合理的物理力学计算参数.采用三维连续介质和离散介质数值模拟方法对岸坡的潜在变形破坏模式进行分析,并选取典型块体开展二维和三维极限平衡计算.结果表明,岸坡整体稳定性较好,但是表层存在向临空面的潜在滑移趋势.建议对岸坡底部的水渠进行封堵,消除临空面,以增加岸坡稳定.

| Abstract: | The west bank slope of certain bridge is rock slope.Affected by the pier loading and the being built Yeshanhe reservior,the slope is likely to be destroyed.On the basis of engineering geology surveying,the hydrological and engineering geological condition of the slope was ascertained.Then the geological model was built and the controlling factors of slope stability were determined.To get reasonable mechanical parameters of rock mass and controlling joints,particular researching work was carried out,and the ... |
