摘要

通过对山西省乡宁县文昌源小区滑坡的分析和研究,提出了利用分段反演参数计算滑坡推力,为滑坡勘查工作中计算滑坡推力提供了一种新的思路。文昌源小区滑坡是典型土岩接触面滑坡,属于现代滑坡重新复活,滑坡复活的主要诱因:一是在滑坡坡脚大量削坡,造成滑坡剪出口处于临空状态,破坏了斜坡原有的平衡;二是滑坡西侧冲沟填埋、修建淤地坝,导致地表汇水入渗补给滑坡体。在充分了解文昌源小区滑坡地质环境条件、滑坡特征及滑坡成因的基础上,建立滑坡体物理模型和数学模型,采用分段反演参数法计算滑坡推力,为后期滑坡治理提供了重要依据。
        On the analysis of the landslide of Wenchangyuan community in Xiangning County,Shanxi Province,it is proposed to calculate the landslide thrust by using the segmentation inversion parameters,which could provide a new thought to calculate the landslide thrust in the landslide exploration.The Wenchangyuan community landslide is a typical soil-rock contact landslide,which belongs to the modern landslide reactivation.The main incentives for reactivated landslide are including:1)A lot of slopes were cut at the foot of the landslide to cause suspending landslide shear cracts,which destroyed the original balance;2)Landfill gully on the west side of the landslide and the construction of silt dams could cause the surface water infiltration to replenish the landslide body.Based on the full understanding of the geological environment conditions,landslide characteristics,and causes of Wenchangyuan community,the physical model and mathematical model of the landslide body were established.The segmentation inversion parameter method is used to calculate the landslide thrust,which provides an important basis for the later landslide control.
