摘要
2011年8月23日,成(都)—雅(安)高速公路K1920+416处发生大型滑坡灾害,导致成雅高速公路断道约15天,该滑坡为"软弱基座式"压致拉裂型滑坡。为加快抢险施工进度,在国内首次采用大直径旋挖钢管混凝土桩进行滑坡应急处治。通过三维有限元数值模拟优化钢管混凝土桩滑坡加固处治方案,并结合工后滑坡地表位移监测,验证了滑坡应急处治工程的有效性,为滑坡应急整治提供一种高效工程治理措施。
On August 23, 2011, a large-scale landslide attacked the Section K1920+416 of Chengdu-Ya an Highway, and the Highway was blocked for about 15 days by this “soft base type” compression-rupture landslide. In order to speed up the construction progress of emergency rescue, the large-diameter rotary-drilled concrete-filled steel pipe piles were adopted for the first time to deal with the landslide in China. This landslide reinforcement scheme of concrete-filled steel pipe pile was optimized by 3D finite element numerical simulation and, with the validity of this treatment for rescue verified by the ground displacement monitoring after the construction, it provided an effective engineering control measure for landslide emergency treatment.
