摘要: 武汉阳逻长江大桥桥址区的工程地质条件复杂, 采用地震反射波法和地震映射波法, 在水域进行工程地震勘探, 查明了桥址区的地质构造、地层岩性分布等工程地质问题, 并对大桥的工程地质条件作出了评价, 为桥型方案的选择提供了重要的地质依据.Abstract: The engineering problems were very complex at the site of Yangluo bridge: developing faults, fold strata and the unclear belt of Xiangfan-Guangji fracture. With the methods of reflection-seismic exploration and mapping-seismic exploration, the geological conditions and the strata lithology are prospected clearly. At the same time the evaluation is made of its engineering geological conditions for selecting bridge scheme.
