摘要
Three aspects of landslide geological model reconstruction were introduced in this article: Geological factors,includes physical structure,geological structure,etc,which reflect the Intrinsic Attributes;Appearance factors,includes landforms,spatial morphology,boundary feature,etc,which reflect the external morphological characteristics;Environment factors,includes earthquake,climate and hydraulic,engineering activities,etc,which reflect influential and predisposing factors.To reconstruct the landslide geological model can follow the next process: analysis of the characteristics—reconstruction of landform—find out the boundary—reconstruction of geological factors—reconstruction of environment factors—reconstruction of landslide geological model.Based on the geological model reconstruction of Laohuzui landslide,many important parameters such as landforms,shear outlet and sliding body structure were obtained.Results showed that the method of landslide geological model reconstruction were technically feasible,and the conclusion of Laohuzui landslide induced factors were well consistent with the results of field investigation.The method can provide the idea for the studies of landslide susceptibility in Xianshuihe fault zone.
