摘要
以广州市某跨海工程为背景,分别对桥梁、隧道2个方案跨越某水道进行论证。经过综合比选表明,桥梁、隧道方案在技术上均可行,但桥梁方案在使用功能、工程投资、后期运营维护成本等方面优势显著,本次桥隧论证推荐采用桥梁方案。对桥梁方案进一步研究比选,通过研究得知(62+104+580+104+62)m混合梁斜拉桥(主跨钢箱梁)方案性价比最高,作为该跨海工程的实施方案。
Taking the cross-sea project in Guangzhou as the background,demonstrates that the two schemes of bridge and tunnel cross a waterway respectively.The comprehensive comparison shows that the bridge and tunnel schemes are technically feasible,but the bridge scheme has significant advantages in terms of functions,engineering investment,and post-operation and maintenance costs.This demonstration recommends the use of bridge scheme.By comparing the bridge schemes,it is found that(62+104+580+104+62)m hybrid girder cable-stayed bridge(main span steel box girder)has the highest performance-price ratio,which is the implementation scheme of the cross-sea project.
