甘肃长输管道某滑坡灾害综合分析及治理研究

ANALYSIS AND GOVERNANCE OF A LANDSLIDE IN GANSU PIPELINE COMPREHENSIVE DISASTER

长输管道是国家重大生命线工程,滑坡灾害可能导致长输管道变形、拉裂、断裂等破坏,对滑坡成灾机理综合分析和稳定性评价是滑坡灾害治理的前提。本文以甘肃地区长输管道的某滑坡体为研究对象,调查分析地质构造、地质地层和地震气候情况,采用因果分析的鱼刺分析法从物、环境、人三个要素对滑坡成灾机理进行分析,并采用传递系数法对滑坡进行稳定性评价。基于滑坡灾害的综合分析成果,从防护、施工、环保和投资四个方面比较选定抗滑桩板墙灾害治理方案,治理实施效果良好。研究成果为类似线性工程的滑坡灾害分析和治理提供参考。

Pipeline is a major national lifeline engineering,landslide hazard may cause longdistance pipeline deformation,crack,fracture and other damage,comprehensive analysis and evaluation of the stability mechanism is a prerequisite for landslide disaster of landslide hazard.Taking a landslide in Gansu province long-distance pipeline for the study,Taking a landslide in Gansu province long-distance pipeline for the study,investigation and analysis of geological structure,geological and seismic stratigraphy climatic conditions,the use of causal analysis of fishbone analysis from material,environment,human three elements of the mechanism of landslide disaster analysis,and the use of transfer coefficient method on landslide stability evaluation.Based on the results of a comprehensive analysis of landslide disasters from protection,construction,environmental protection and investment in four antislide Piles Compare Selected disaster management program,the implementation of governance to good effect.Similar research is landslide hazard analysis and control of linear engineering reference.
