摘要
结合上海青草沙水源地原水隧道工程的设计过程,探讨采用长距离盾构隧道建设大型原水输送隧道的适应性,解决长距离输水隧道工程设计过程中高内水压及防渗漏等问题,对设计实施过程中的一些技术要点提出改进的相关建议,为长距离输水隧道的设计提供一些更为合理和可行的措施。
The feasibility to build large-scale water-supplying tunnels by long-distance shield tunneling method is discussed,the problems,such as the high internal water pressure and the water leakage,encountered in the design of the long-distance water-supplying tunnel bored by shield machines are solved and optimization recommendations are made to the design of the tunnels,with the design of Qingcaosha Water-supplying Tunnel in Shanghai as an example.The paper can provide more rational and practical references for the design of other long-distance water-supplying tunnels bored by shield machines in the future.
