摘要
研究区位于潞西盆地西侧,设计泛亚铁路西线大理至瑞丽段经过该区。对该区的工程地质特征及其评价工作是作出合理、可靠的工程设计的基础。龙陵-瑞丽断裂是滇西地区一条深切超壳的活动断裂,对该断裂在研究区内的展布及其深部延展情况进行探测尤为重要。本文通过遥感图像(ETM+和SPOT)对断裂进行宏观解译,并在第四系覆盖区利用EH-4电磁成像系统对断裂深部延展情况进行探测,同时结合地面详细调查,获得龙陵-瑞丽断裂潞西段的发育特征,这为铁路工程设计与施工提供了重要的资料。
The study area is located west of the Luxi basin where the west branch of the Pan-Asia railway, from Dali to Ruili, is designed to traverse. The research and evaluation of its geological characteristics are basal to reasonable and reliable railway design. As the Longling-Ruili fault is a deep active fault in west Yunnan, it is very important to detect its development and extension at depth. Macroscopical interpretation of the fault by analyzing the re- mote sensing image including ETM＋ and SPOT was carried out. The fault＇s extension at depth in the Quaternary coverage area was also investigated by EH-4 electromagnetic imaging system. Combining with a detailed surface survey, we concluded the major characteristics of the Longling-Ruili fault at Luxi area which provides information important for the design and construction of the railway.
