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 on the west side of the Luxi Basin and designed to cross the Dali-Ruili section on the west line of the Pan-Asia Railway. The engineering geological features and evaluation of the area are the basis for making reasonable and reliable engineering design. Longling-Ruili fault is a deep-crusted active fault in the western Yunnan region. It is particularly important to explore the distribution of the fault in the study area and its deep extension. In this paper, we interpret the fracture by remote sensing images (ETM + and SPOT), and use the EH-4 electromagnetic imaging system in the Quaternary coverage area to detect the deep extension of the fault. At the same time, with the detailed investigation of the ground, Longling-Ruili fault Luxi section of the development characteristics, which provides the railway engineering design and construction of important information.
