综合勘探在武汉军山长江大桥勘察中的应用

单一的勘探手段很难适应高速公路基本建设对勘察设计的高水平、高质量和高效率的要求。将钻探、地震勘探、重力勘探、磁法勘探、电视测井、声波测井等勘探手段综合运用于武汉军山大桥地质勘察中，不但精确探明了桥墩处地层岩性的风化程度，裂隙的位置、产状、规模，岩石完整性等，准确提供了岩石的力学参数，而且缩短了勘察周期，降低了成本。

COMPREHENSIVE GEOLOGICAL EXPLORATION METHOD APPLIED IN JUNSHAN YANGTZE BRIDGE, WUHAN

A single prospecting method cannot satisfy the requirement of high level, high quality and high efficiency in a survey. While the application of the comprehensive geological methods: drilling, seismic, gravity and magnetic explorations, TV logging and sound logging, in Junshan Yangtze bridge, Wuhan not only resulted in an accurate prospecting of the weathering of the rocks, the positions of the fissures, their occurrences and scale, etc, which provided the mechanical parameters of the rocks, but also shorted the period of the exploration and thus reduced the cost of the project.
