| 摘 要： | 深圳地铁12号线和平站下穿穗莞深城际高速铁路桥梁,地处填海区软弱淤泥地层,为减少地铁车站深基坑施工对城际铁路桥梁结构的影响,采取对桥梁基础进行隔离桩保护、支护结构加强等辅助措施,并利用钢支撑轴力伺服系统实时控制地铁基坑变形。目前地铁主体工程已完成,结果表明,在采取以上措施后,满足车站基坑施工与高架桥变形的安全性要求。

| Abstract: | The Peace station of Shenzhen metro line 12 under the Guangzhou-Dongguan-Shenzhen intercity high speed railway bridge is located in the reclamation area of soft silt stratum.In order to reduce the influence of metro station deep foundation pit construction on intercity railway bridge structure,the auxiliary measures have been taken to protect the bridge foundation with isolated piles and strengthen supporting structure,and take the steel support axial force servo system to real-time control metro foundation pit deformation.At present,the main metro project has been completed.The results show that the safety requirements of foundation pit construction and viaduct deformation can be satisfied after the above measures are taken. |
