摘要
为了评价峡谷区岩质桥基岸坡稳定性,并确定桥基合理埋置位置,综合采用初步地质评价、经验公式法、岸坡应力场有限元模拟及强度分析对宜昌—万州铁路清江大桥岸坡的稳定性进行评价,确定清江大桥宜昌端桥基设置位置为埋深10m,距岸坡边缘16m,在此桥位下,岸坡岩体满足强度要求,岸坡整体稳定,并表明该系统方法具有工程实用价值。
To confirm the rational laying position of bridge piers of bridge bank slope in gorge area,this article adopts elementary field geological evaluation,empirical formula method,simulation of slope stress state with FEM and rockmass strength judgement.Then the author applies this systematic method to stability evaluation of bank slopes of Qingjiang River in YichangWanzhou Railway.The depth of piers on Yichang bank should be 10 m and the piers should be at least 16 m away from the slope edge.Applying results indicate this method is valuable to be applied in rocky slope engineering.
