综合物探在鄱阳湖铁路特大桥勘察中的应用

鄱阳湖铁路特大桥桥址位于鄱阳湖入长江的交汇处。该区地质情况复杂,断裂构造十分发育,因此地质勘探对桥址方案的比选显得尤为重要。此次有效地利用了综合物探,采用多种方法查明了岩性分区和地质构造格局,取得了良好的地质效果。充分显示了综合勘探、综合物探的优势。

THE APPLICATION OF INTEGRATED GEOPHYSICAL PROSPECTING TO THE EXPLORATION OF POYANG LAKE GIANT RAILWAY BRIDGE

The Poyang Lake giant railway bridge is located where the Poyang Lake enters the Yangtze River. As the area has complex geological conditions and well-developed faults, the selection and comparison of schemes for bridge sites through geological exploration seem especially important. By effective utilization of integrated geophysical prospecting and employment of various methods, the authors found out lithologic divisions and tectonic framework, thus obtaining fine geological effects. The results fully demonstrate the advantages of integrated exploration and integrated geophysical procpecting.
