摘要
肇庆大桥拟建于场地岩溶极发育区,地形、地质情况相对复杂。通过研究,提出了利用多种地球物理勘探方法相结合的综合物探方法来探查岩溶区的岩溶分布特征,对大桥复杂不良地质构造进行快速准确的判定,作出科学划分。
Zhaoqing Bridge was planned to be built in the area with extreme karst development,and subject to complex topographic and geological conditions.Through the research,a comprehensive geophysical prospecting method combining various geophysical prospecting methods was proposed to explore the karst distribution characteristics in this area.This method could give quick and accurate determination on the complex and unfavorable geological structures of the bridges,and then make the scientific division.
