四川省绵竹至茂县公路工程地质遥感调查与评价

Remote Sensing Survey and Evaluation of Engineering Geology along Mianzhu-Maoxian Highway in Sichuan Province

以绵竹至茂县公路沿线为研究区,应用遥感技术调查走廊带内地质灾害发育分布状况,结合公路勘察需要,从工程地质角度出发,选择地质灾害类型、分布位置、规模、稳定性/易发性、运动方向5个方面作为地质灾害对线路影响的评价指标,并建立针对不同灾害类型的线路影响程度评价方法,评价结果为公路选线和后期详勘奠定了基础。

Taking the area along Mianzhu-Maoxian highway in Sichuan as the research area, the remote sensing technology is used to probe into development and distribution of geo-hazards in the areas along the highway. From the view point of engineering geology, the types, location, scale, stability （vulnerability） and direction of movement as the evaluation indicators of impacts of geological hazards on the highway, the method for evaluation of the impacts of different types of disasters on the highway is worked out. The results of evaluation will lay a good foundation for the route selection and further detailed investigation of highway.
