摘　　要：不同的地下水状态会蕴含多变的地质情况,从而可能给管廊施工过程带来不可预知的影响,同时地下水富集会造成管廊的渗水现象,影响管廊耐久性和适用性。为减少管廊施工受地下水作用的影响,保证管廊的有效长远使用,对管廊施工中地下水进行及时探测、有效降排是设计与施工的关键所在。Different groundwater state should contain various geological conditions, which can bring unpredictable utility tunnel construction process. Meantime, groundwater enrichment can cause utility tunnel seepage, which affects the durability and applicability of utility tunnel. In order to reduce the effect of groundwater on utility tunnel construction, and ensure the effective long-term use, doing the timely detection, effectively reducing the discharge of groundwater are the key to the design and construction for the utility tunnel construction.
