台阶边坡失稳导致在建构筑物开裂后的支护方案分析

Analysis of Emergency Treatment and Permanent Treatment of Rock Slope After Instability

在斜坡上进行工程建设时,切坡会形成台阶,边坡没有及时进行支护,导致边坡失稳,在建的房屋出现裂缝。当务之急是确保边坡不会大规模滑动,应急处置措施是采用毛石混凝土挡墙来压脚;其次,为了保证房屋裂缝不再增大,通过全覆盖的位移监测,采取测绘、钻探、室内试验、现场直剪试验、监测等技术综合研判,选择经济合理的治理支护措施。

Engineering construction activities on slopes,the cut slope will form steps,the slope was not supported in time to resulting in slope instability, cracks appear in houses under construction. The priority is to ensure that the slope does not slip on a large scale, the emergency treatment measures are to use rubble concrete retaining wall to press the foot of the slope;secondly, in order to ensure that the cracks in the house do not increase, through the displacement monitoring of full coverage, after the deformation trend of the rock slope slows down, adopt surveying and mapping, drilling, laboratory test, field direct shear test, monitoring and other technology comprehensive research and evaluation,choose the economic and reasonable permanent treatment measures.
