摘要  随着城市交通的快速发展, 在长三角等河流众多的区域建设大断面短距离河底隧道的需求急剧增加。采用盾构法在河流下方进行隧道施工时, 为了满足线路坡度要求, 河底段覆土往往较浅, 而且盾构在河流驳岸处推进时, 覆土深度变化较大, 切口水压较难控制, 从而增加了施工风险和施工技术难度, 成为影响工程安全的关键问题。文章以江阴澄江西路隧道工程为背景, 首先分析了河底浅覆土和河流驳岸处的施工风险; 其次, 为了降低大直径泥水盾构隧道穿越河流段的施工风险, 提出了对闸桥河驳岸边及河底进行加固的技术措施; 同时, 在盾构掘进过程中选取合适的施工参数并采取相应的施工控制措施, 综合采用多种手段为盾构顺利穿越河流段施工提供了有 力保障, 可为类似工程提供借鉴。

Abstract: With the rapid development of urban traffic, there are increasing needs for short and large-section traffic tunnels in the Yangtze River delta area with many rivers in China. To meet the slope requirements, the depth of overburden under river is usually small, and the pressure at tunnel face is difficult to be controlled when tunnel crosses under the river revetment where the overburden varies largely, which increases the risks and difficulties of construction and becomes a key issue concerning project safety. Based on the Chengjiangxilu tunnel in Jiangyin, construction risks were analyzed in respects of small overburden and the river revetment; in order to reduce construction risks of the large-diameter slurry shield tunnel crossing river, some construction techniques were proposed for rein? forcement of river revetment and riverbed of Zhaqiao River; and appropriate construction parameters were selected and construction control measures were adopted in the process of shield construction.
