| 摘 要： | “4.20”四川芦山地震诱发了大量次生地质灾害，导致宝兴县两河口崩塌危岩体发育，威胁进出地震灾区的生命线工程省道S210，威胁周边企事业单位及居民人数超过500人,严重影响了抗震救灾和灾后的恢复重建。在充分考虑治理区自然情况的基础上，采取预应力锚索锚杆支护，桩板拦石墙与钢轨障桩联合治理，解除了在暴雨作用下，治理区危岩体顶部、崩坡积层和下部坡面上存在的危石灾害，解决了被动网立柱抗弯能力较弱的问题，形成障桩起保护作用。为宝兴县灾后重建赢得了时间。

| Abstract: | Lushan earthquake on April 20 led to a large number of secondary geological hazards, such as the development of dangerous rock mass collapse in Baoxing country, by which the lifeline provincial road S210 and more than 500 people were threatened, the earthquake relief work and post-disaster reconstruction were affected. Based on the full consideration of the nature situation of restoration region, pre-stressed anchor cable bolting, sheet pile retaining wall and rail barrier pile were adopted to form protective barriers and piles, which controlled the dangerous rock disasters at the top of dangerous rock mass in controlling region, colluvial deposit layer and the lower slope in the influence of rainstorm, and also overcame the weak bending resistance of passive network column. These measures won the precious time for the post-disaster reconstruction in Baoxing County. |
