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.
