TM影像遥感技术在武汉四环线工程中的应用研究

武汉市四环线工程位于三环线与绕城高速公路之间,处于江汉平原东部,以第四系沉积为主,地势总体较为平坦,隐伏地质构造发育.利用遥感图像宏观、逼真、直观、丰富的信息,为四环线工程的选线、工程可行性研究、路线工程地质条件评价和工程初步设计提供参考.遥感解译易于发现常规地质调查难以发现的地质现象,特别是隐伏断裂及不良地质体可能对工程产生的影响,建议在建设施工阶段采取必要的处理,如工程地质勘探、路基加固等措施,为四环线工程建设提供重要的基础资料.

Application Study of TM Remote Sensing Technique in Project of the Fourth Ring Road in Wuhan

Between Third Ring Road and highway around Wuhan,Project of the Fourth Ring Road is located in east of the Jianghan Plain,where is mainly covered by Quaternary strata.There is generally smooth terrain and many concealed geological structures in study area.By mean of macroscopic,vivid,visual and abundant information of remote sensing images,it is provided reference to site selection,feasibility study,and evaluation of engineering geological conditions as well as project preliminary design.By remote sensing interpretation,some geological phenomena can be found that are usually undiscovered in conventional geological survey,such as concealed faults and geological bodies,which could damage to the Project.So it is suggested that to take necessary treatment measures in construction stage,for instance engineering geological prospecting,subgrade reinforcement,etc.Remote sensing interpretation can provide important,elemental information to Project of the Fourth Ring Road in Wuhan.
