在我国西部地区,由于受特殊的地形地质条件影响,滑坡灾害已成为制约地区经济持续稳定发展的因素之一,其中多级滑坡由于其形成机理复杂,在工程建设中往往造成计算所得的剩余下滑力过大,导致治理非常困难;以贵州省沿河县沙子镇龙家岩多级滑坡为例,通过野外调研、钻探、深部位移监测等资料着重分析了滑坡的形成机理,以此为据采用分级治理的思路对滑坡作了稳定性评价,提出了以抗滑桩为主的治理方案,最后采用ANSYS软件对h型抗滑桩的受力特征进行了有限元计算。该分析思路对类似工程的研究具有参考价值。
In western China, landslide disaster has become one of the factors restricting the sustained and stable development of economy in the western region. Because of its complex formation mechanism, the multi-stage landslide tends to cause the remaining surplus in engineering construction to decline As a result, it is very difficult to control the landslides. Taking the Longjiayan multi-stage landslide in Shazi Town, Yanhe County, Guizhou Province as an example, the formation mechanism of landslides is analyzed emphatically based on field investigation, drilling and deep displacement monitoring. Based on the idea of grading control, the stability of landslide was evaluated, and the control plan based on anti-slide piles was put forward. Finally, the finite element method was used to calculate the force characteristics of h-type anti-slide piles by ANSYS software. The analysis of ideas for similar projects with reference value.
