芜湖长江大桥地质综合勘探模式研究

针对芜湖长江大桥选址过程中存在的主要工程地质问题（包括软弱地基、隐伏断层、区域稳定性），综合运用3S（GPS、GIS和RS）、地面测绘、物探和原位测试等勘探技术有效地解决了这些问题。研究表明，综合勘探模式比传统的勘探方法更灵活、更精确，提供的资料更符合实际，在特大桥工程地质勘探中推广和应用这种综合勘探模式，能促进勘探工作的规范化、数字化和自动化，降低工程成本，大大缩短建设投资的回报周期。

STUDY ON COMPREHENSIVE GEOLOGICAL EXPLORATION MODEL IN WUHU YANGTZE BRIDGE

By ways of 3S (GPS, GIS, RS), geodesy, geophysics exploration and field testing, main geological problems, such as soft base, concealed fault and area stability, are solved effectively. It has proved that the comprehensive exploration model is better than traditional prospecting, and that it will propell the exploration into standardization, digitization and automation. Moreover, the investment and return period could be reduced to a great extent.
