云南宣威-曲靖段高速公路遥感选线应用研究

在国家高速公路G56杭州至瑞丽公路宣威-曲靖段前期选线研究中,以日本ALOS卫星遥感图像为主要信息源,对其进行遥感数据处理。依据遥感解译结果,结合野外调查验证资料,对宣威-曲靖段进行了工程地质区划分与评价,确定地质灾害较易发区：滑坡区、地表岩溶塌陷区、隐伏岩溶区、煤矿采空塌陷区;依据公路工程评价因素,将工程区划分为4个工程地质区、9个工程地质亚区。通过对线路走廊带及主要工点工程地质条件的评价,对工程设计推荐线与三段局部比较线（C、D、E）方案进行优选,最终确定了在推存线方案中可考虑采用C、E局部方案的理想线路。

Remote Sensing Route Selection Applied Research in Xuanwei-Qujing Sector,State Expressway G56

In the earlier stage route selection research of Xuanwei-Qujing sector of state expressway Hangzhou-Ruili G56,using remote sensing images of Japanese ALOS satellite as main information source,carried out remote sensing data processing.Based on the interpretation results,combining with site investigating verification data,have carried out Xuanwei-Qujing sector engineering geological zoning and assessment.Geological hazard susceptible areas of landslide,surface karst collapse,hidden karst and coalmine gob have been determined.Based on highway engineering assessing factors,have divided project area into 4 engineering geological regions,9 subregions.Through engineering geological assessment of route corridor zones and main construction sites,carried out optimization of project design commendatory routes and three local alternative line（C,D and E） schemes,finally ideal C and E local schemes in commended route scheme have been determined.
