摘要
希腊里翁-安蒂里翁大桥位于地壳运动的强地震带,跨越深水的海峡和厚沉积土,在十分困难条件下建桥,确实对建设者是一个极大的挑战,在该桥设计中采用了全漂浮五跨连续斜拉桥,基础采用了在加固地基上铺设卵石垫层的沉箱基础解决大的水平位移。在施工中采用了大型浮吊安装上塔柱和主梁,在船坞中预制和浮运沉箱基础等海上作业的方法。他们的创新精神和思路值得我们借鉴。
Located at the strong seismic zone of tectonic movement, and erected across the strait with deep water and thick soil strata, the Rion-Antirion Bridge, a 5-span total floating continuous cable-stayed bridge having been built under extremely difficult conditions is indeed a formidable challenge to the Bridge builders. The caisson foundations of the Bridge in the strait are rested on reinforced soil with gravel layers to mitigate large horizontal movement. Lots of offshore construction methods have been adopted, such as erecting of the upper pylon shafts and main girders with huge floating cranes, prefabricating of the caissons in docks and floating of the caissons to their destinations. The innovations and ideas of the builders afford really helpful experiences deserving to learn.
