文章以闽清县东桥镇某边坡工程为研究对象,总结了该边坡地形地貌及崩塌体形态特征,对典型剖面采用圆弧法自动搜索最危险滑动面进行稳定性验算,获得了不同剖面的稳定性状态。针对边坡状态,提出了抗滑桩治理措施,并通过数值手段对抗滑桩的治理效果进行分析。研究表明,该崩塌属小型土质崩塌,崩塌体主要为残积粘性土、全风化凝灰熔岩。拟治理灾害点目前整体处于基本稳定~临界状态。在降雨等因素影响下可能发生滑塌灾害,其危险性、危害性较大。采用抗滑桩后边坡的变形显著减小,稳定性显著提升。文章研究方法和结果可为类似边坡治理工程提供指导和借鉴。
This paper takes a slope engineering research object in Dongqiao Town,Minqing County,and first summarizes the topography and morphological characteristics of the slope through field geological mapping and field drilling.Furthermore,the stability of the typical profiles was calculated by using the arc method to automatically search for the most dangerous sliding surfaces,and the stability states of different profiles were obtained.According to the slope state,the anti-slide pile treatment measures were proposed,and the treatment effect of the anti-slide pile was analyzed by numerical means.On the study surface,the collapse is a small soil collapse,and the collapse body is mainly residual cohesive soil and fully weathered tuff lava.At present,the disaster points to be treated are basically stable~critical,especially under rainfall conditions.Under the influence of rainfall and other factors,landslide disasters may occur,which is dangerous and harmful.After the use of anti-slide piles,the deformation of the slope is significantly reduced,and the stability is significantly improved.The research methods and results of this paper can provide guidance and experience for similar slope engineering.
