某堤防整治工程地质灾害危险性评估与防治措施探讨

Discussion on Geological Hazard Assessment and Prevention Measures for a Certain Embankment Regulation Works

通过对某堤防整治工程建设用地进行调查,预测评估区内主要地灾类型为地面沉降、边坡滑坡。在此基础上,运用圆弧滑动、毕肖普法等方法,对上述地质灾害危险性开展了评估。总体分析认为评估区现状地质灾害不发育,预测地面沉降发育程度中等,危害程度中等~大,危险性中等~大。堤防边坡滑坡发育程度中等~强,危害程度中等~大,危险性中等~大,并针对性地提出了具体的防治措施,为后期工程建设和地灾防治提供了依据。

By investigating the construction land of a certain embankment regulation works,it is predicted that the main types of geological disasters in the assessment area are surface subsidence and slope landslides.According to these,methods such as circular sliding and Bishop's method were used to evaluate the risk of geological hazards assessment above.Overall analysis suggests that the current geological hazards in the assessment area are not well-developed,and predicts that the degree of surface subsidence is medium,the degree of hazard is medium to large,and the danger is medium to large.The development degree of embankment slope landslides is medium to strong,the degree of hazard is medium to large,and the danger is medium to large.Specific prevention and control measures have been proposed in a targeted manner,providing a basis for later engineering construction and disaster prevention.
