| 摘 要： | 浙江上虞—三门高速公路是连接浙东南沿海经济圈与浙中部地区的重要交通枢纽,2011年10月26日,该高速公路管理处养护人员发现桩号K270＋700处边坡有明显变形现象。本文在现场调查分析的基础上对上三高速公路K270＋700边坡进行了系统研究,研究分析表明,该边坡的破坏模式为两组控制性结构面相切产生的楔形块体沿交线方向发生滑移破坏。最后,针对边坡的破坏模式和现状情况提出应急抢险和永久性治理相结合的综合治理措施。

| Abstract: | Shangyu-Sanmen highway in Zhejiang provence is the key transportation junction connecting the central re- gion and the economic circle in southeast coast. However, a maintenance personnel of administrative office found out the apparent deformation at the pile of k270 ＋700 on October 26th 2011. Based on the field investigation and analy- sis, this paper makes a systematic study on the slope deformation. The studies show that the failure mode is wedge slip fracture along the line of intersection by two control discontinuities. Therefore, comprehensive support method eombined with temporal and permanent control measures are proposed according to the slope failure mode and current situation. |
