摘要
对天津西站至天津站地下直径线从海河东、西两岸穿越金刚桥的技术方案进行了研究,运用数值模拟分析了盾构施工过程中土体扰动对桥梁基础及桥梁安全性的影响,得出了海河东、西两岸方案穿越金刚桥在技术上皆可行,海河西岸方案更为合理的结论.
In this paper, two technical schemes of shield tunneling under Jin-gang Bridge from east and west of Hai-he River in Tianjin Underground Zhi-jing Line （from Tianjin West Railway Station to Tianjin Railway Station） are researched, and the effects of ground movements during shield tunneling on the foundation and safety of Jin-gang Bridge are analyzed through numerical simulation. Then a conclusion is drawn in the paper that even though the two schemes are both feasible, yet the scheme from west of Hai-he River has better feasibility.
