摘要:
泾河下游台塬区黄土滑坡频繁发生,曾造成严重的人员伤亡和经济财产损失。以“泾河南岸泾阳段黄土滑坡调查评价”项目为依托,对区内滑坡的类型及分布情况进行了较为详细的野外调查。根据调查结果将黄土滑坡按诱发因素及运动特征划分为灌溉流滑型黄土滑坡、灌溉滑动型黄土滑坡、侵蚀滑动型黄土滑坡、侵蚀滑塌型黄土滑坡及开挖垮塌型黄土崩塌5个类型。在此基础上对黄土滑坡的时空分布规律进行了研究,结果表明:区内黄土滑坡的时间分布特征表现为黄土滑坡日趋频繁和春季多发,空间特征表现为黄土滑坡多塬段群发和区域破坏模式差异,这些特征系人类工程活动与其它地质环境条件耦合作用的结果。灌溉诱发型黄土滑坡具有典型的多序次破坏特征,从一定程度上体现了滑坡在时间与空间上的相互关系。
Abstract:
Loess landslides have occurred frequently in the south plateau of lower Jing River,resulting in severe property loss and casualty.This study is based on detailed investigations and evaluation of geological disasters in Jingyang and intensive field investigations were carried out on the classification of landslides and the spatial distribution.According to the geological disaster investigation results,the following types of loess landslides were classified irrigation-flowslide type,irrigation-slide type,erosion-slide type,erosion-slump type and excavation collapse type.On the basis of the analysis,the conclusion is as follows.Loess landslides in this area show the temporal characteristics of a growing number and high risk in spring,the spatial characteristics of clustering and variation.Irrigation triggered type also shows the spatial and temporal characteristics of repeatedly failure.
