基于典型线路地质灾害调查成果进行地质灾害区划评价的研究

根据影响区域地质灾害发生的地质因素、地形因素、诱发因素和人为因素,在工作区上选取典型线路开展地质灾害发生发育状况调查,根据调查成果总结规律,提取影响因子,建立区域地质灾害评价指标体系,对典型线路穿越的评价试验区进行地质灾害区域评价,验证线路成果应用于区域地质灾害评价的可行性,对于调查人员无法涉足、遥感技术难以应用的地区的地质灾害的评价工作有重要价值。

Study of the Geo-hazards Zonal Assessment Based on Typiclal Route's Survey Results

On the basis of geologic factor,terrain factor,inducing factor and artificial factor that affected the occurrence of geo-hazards,we selected the typical route,surveyed the status of geo-hazards,summarized the rules,extracted the factors,created the indicator system of geo-hazard zonal assessment,assessed the status of geo-hazards in the test zone through which the typical route passed,testified the feasibility of applying the route survey results in the assessment of zonal geo-hazards,which is of great value to the districts where surveyors cannot access and the remote sensing technique isn't applicable.
