佛山市汾江路南延线工程干坞设计

干坞是沉管隧道设计的重点和难点,其设计方案合理与否直接影响工程造价、工期。文章以佛山市汾江路南延线工程干坞设计为例,介绍一种新型的旁建干坞方案,即干坞与岸上主体基坑并排同期实施、管段预制与岸上段主体结构同步进行。该方案成功地解决了满足工程工期的大型干坞场地问题,并避免了轴线干坞工期长、独立干坞造价高等缺点。

The Dry Dock Design of the Fengjianglu South Extension Project

Dry dock design is very important and difficult for an immersed tunnel,as the design scheme will directly affect the construction cost and timeline.Using the design of the dry dock for the Fenjianglu South Extension Project in Foshan as an example,this paper illustrates a new scheme for a side-built dry dock with the dry dock and main body foundation pit constructed simultaneously and the segment prefabrication and major structure on the bank completed at the same time.This new scheme solves problems concer...
