摘要
对武当山隧道进口处Ⅰ号和Ⅱ号滑坡稳定性主要影响因素进行了分析,采用传递系数法对Ⅰ号和Ⅱ号滑坡在天然及饱和状态下的稳定性进行定量计算,利用Flac3d软件对Ⅰ号滑坡在天然及饱和状态时的应力应变进行数值模拟研究.综合分析认为,降雨入渗是加剧武当山隧道进口处滑坡活动触发因素.为保证襄渝铁路运营安全,建议对Ⅰ号滑坡进行削坡处理,对Ⅱ号滑坡在前缘设置抗滑桩进行处理.
The main influence of stability of landslides on Wudang mountain tunnel entrance of Xiangfan-Chongqing rail way is analysised qualitatively, and the stability of landslide Ⅰ and landside Ⅱ in natural state and saturated state are calculated by the transfer coefficient method. Besides, The stress and strain of landslide I in natural state and saturated state are simulated by the Flac3d. It comes to the conclusion that rainfall infiltration is the trigger factor of landslide on wudang mountain tunnel entrance.To ensure the operation safety of Xiangfan-Chongqing rail way, this papper suggests that cutting slope for landslide Ⅰ and setting anti-slide pile for the frontal part of lanslide Ⅱ.
