京沪高速铁路南京长江大桥综合勘探

COMPREHENSIVE INVESTIGATION ON NANJING YANGTZE RIVER BRIDGE OF THE BEIJING-SHANGHAI HIGH-SPEED RAILWAY

即将兴建的京沪高速铁路是一条重要的铁路干线，也将是我国第一条高速铁路。我院在京沪高速铁路南京长江大桥桥址前期勘察中采用了以水域浅层地震剖面、陆地地震反射勘探为主的综合勘探方法，取得了较好的地质效果。结合该桥址综合勘探实例，本文综合分析了物探、钻探的资料，论述了二者相辅相成、缺一不可的关系。

he Beijing-Shanghai high--speed railway which will be built in the near future is an important railway. During the site investigation of the Naming Yangtze River Bridge of this railway,the water area shallow seisdric profile method and the land shallow seismic reflection method are mainly employed. Based on the bridge comprehensive investigation exampie,the geophysical exi' ')ration,the drill method and their relationships are analysed in this paper.
