白鹤滩金沙江大桥主要地质问题及勘察方法

Main geological problems and investigation methods of Baihetan Jinsha River Bridge

通过对白鹤滩金沙江大桥主要地质问题分析,确定了以地质调查与测绘、钻探、声波测井、电视测井、室内试验为主的综合勘察方法,对桥址区工程地质条件进行勘察,查明了场区工程地质条件,为大桥设计方案优化调整提供了地质依据,目前桥梁已经通车运营,对同类项目的勘察具有参考意义。

Based on the analysis of the main geological problems of Baihetan Jinsha River Bridge,the comprehensive investigation methods including geological survey and mapping,drilling,acoustic logging,television logging and indoor test are determined to investigate the engineering geological conditions of the bridge site and find out the engineering geological conditions of the site,so as to provide the geological basis for the optimization and adjustment of the bridge design scheme.At present,the bridge has been put into operation,and it has reference significance for the investigation of similar projects.
