摘要
青草沙水源地原水工程长兴岛域输水隧道是国内首条单衬砌受高内水压的盾构法隧道,其穿越了黏土、粉性土及砂土等地层,受规划现状影响,隧道穿越大堤、河流、立交、地道、沪崇苏大通道等控制性构筑物。隧道采用盾构法施工,多方论证后采用单层衬砌的混凝土管片,在工期、经济上均达到最大的优化。
The water conveying tunnel in Changxing Island of Qingcaosha Raw Water Project is the first single lining high internal water pressure shield tunnel of China. This tunnel goes through the clay, silty soil and sandy soil stratums, and is affected by the status of planning. This tunnel crosses the controlled structures of levee, river, interchange, subway, Shanghai-Chongming-Qidong Channel. This tunnel is constructed by shield method. After many arguments, the use of single lining concrete segment is mostly optimized in the construction period and economy.
