宁波大榭第二大桥工程水上勘察施工组织

Aquatic Survey Construction Organization of Ningbo Daxie No.2 Bridge Project

宁波大榭第二大桥位于宁波北仑及大榭岛,横跨黄峙江,大桥主墩皆位于黄峙江中,勘察施工需在水上进行。由于黄峙江水文地质条件及桥址处环境条件复杂,对勘察施工提出了较高要求。该文介绍了针对大榭二桥的工程特点,通过精心组织,尤其是水上安全施工组织措施,使勘察施工顺利完成,为类似工程积累了经验。

Ningbo Daxie No.2 Bridge is located in Ningbo Beilun and Daxie Island and spans Huangzhi River. The main piers of the bridge are all placed in Huangzhi River. Its surveying construction is required to do in the water. The requirement of the surveying construction is higher because of the complicated hydrological geological condition of Huangzhi River and the complex environmental condition at the bridge location. The article introduces the engineering characteristics of Daxie No.2 Bridge and the aquatic safety construction organization measures to make the surveying construction smoothly completed able to accumulate the experience for the similar projects.
