摘要:
二庄科滑坡位于延安市宝塔区二庄科北区,为中型黄土滑坡.为确保二庄科旧城改造规划区的居民人身财产安全,在野外调查的基础上分析了该滑坡的工程地质特征,探讨其变形特征,通过数值模拟揭示了该滑坡的形成机理.结果表明人类工程活动的削坡作用使得坡体形成下缓上陡的地形特征,为滑坡的发生提供了一定的基础条件.同时,堆积层节理裂隙发育、物质结构松散、渗透性差、遇水易软化等均为影响边坡变形的重要因素.人类工程活动是滑坡发生最主要的诱发因素.充分认识滑坡的变形特征及形成机制,有利于滑坡治理措施的合理选择,对同类型的滑坡治理具有借鉴意义.
Abstract:
ErZhuangKe landslide is located in the north of ErZhuangKe,Baota District,Yan'an City,and is a medium|sized accumulation loess landslide.In order to ensure the safety of residents and property in ErZhuangKe urban reconstruction area,the engineering geological characteristics of the landslide are analyzed on the basis of field investigation,the deformation characteristics are discussed,and its forming mechanism is revealed by numerical simulation.The results show that the slope|cutting effect of human engineering activities makes the slope form a gentle upward and steep terrain feature,which provides certain basic conditions for the occurrence of landslides.At the same time,the development of joint fissures in the accumulation layer,loose material structure,poor permeability,and easy softening in water are all important factors affecting the slope deformation.But human engineering activity is the main inducing factor of landslide.Therefore,fully understanding the deformation characteristics and formation mechanism of landslides is conducive to the reasonable selection of landslide management measures and has reference significance for the same type of landslide management.
