中文摘要:
      年7月16日上午9点,青藏高原阿曲河左岸多年冻土区某公路改建工程K101+170处发生滑坡,冲断了原有道路路基,并危及原有公路、坡前便道及过往车辆行人安全。通过对该滑坡的野外地质调查和分析研究,基本查明该滑坡的形成机理,认为其属于冻土区大型牵引式滑坡。并利用geo-studio软件进行了冻融作用下的稳定性分析,根据计算获得的蹦滑距,提出了相应的治理措施。
英文摘要:
      At 9 a.m. on July 16,8, a landslide occurred at K101+170 of a highway reconstruction project on the left bank of the Qu river in the permafrost region of the Qinghai-Tibet plateau, breaking the original roadbed and endangering the safety of the original highway, the passing vehicles and pedestrians.Through the field geological survey and analysis of the landslide, the formation mechanism of the landslide is found out, and it is considered to be a large scale towed landslide in the permafrost area. The stability analysis under freeze-thaw was carried out with geo-studio software, and the corresponding treatment measures were proposed based on the calculated skates
