南水北调中线西四环暗涵工程设计要点剖析

西四环暗涵工程以其工程难度大、工期长成为南水北调中线工程的主要控制性工程之一.在设计中将浅埋暗挖技术首次应用于大流量有压输水暗涵,进一步拓展了适用于城市输水工程的工程技术手段.对结构及全封闭防水层的设置进行了专门的论证分析,突出了监控量测的重要地位,并将第三方监测引入到水利工程中.

Analysis on design of the buried culvert under the fourth ring road in the Middle Route of the South-to-north Water Transfer Project

The constructions in was used in the buried culvert under the South to North construction of high a new construction method in urban the west fourth ring road is one of the most important Water Transfer Project. Shallow buried-tunnelling method discharge pressure culvert for the first time and developed water distribution project. The design carried out special analysis on the structure and the setting of waterproof layer, highlighted the importance of monitoring, and introduced the third party monitoring to the hydraulic engineering.
