水域地震反射波法在探查跨江桥址断裂构造中的应用

The Application of Water-area Seismic Reflection Method to Exploration of Faultage Structure under Bridge Location over River

结合江顺大桥的勘察实践,介绍水域地震反射法在探查断裂构造的地质效果,说明水域地震反射法可有效探明断裂构造的分布范围和构造特征,为桥位的选择及桥型方案的比选提供必要的地质依据。

Combining with the practical work of the Jiang-shtm bridge,this paper gives introduction and production of the water-area seismic reflection method using in protecting geologic structure.This method can be used in explore the distribution and character of faultage structure.The work can give necessary geology basis for selectifig the bridge location and bridge style.
