摘要: 在城市软弱区域修建地铁工程,不可避免地遇到下穿市政道路。依托某地铁隧道下穿市政道路工程中诱发的涌泥灾害,通过工程地质与水文分析,提出了综合治理措施,有效地治理了涌泥地质灾害和减小了地铁隧道施工对市政道路运营的影响,为类似工程提供了重要参考。

Abstract: Tunnels in the urban soft soil area are frequently undercrossing the municipal streets. This paper provides a case history of emergency response of the sudden mush rush in during the tunnel excavation underneath a street. The comprehensive mitigation measures were proposed based on the subsurface geotechnical and hydrological conditions. The emergency response and the mitigation method effectively reduced the impact of the tunnel excavation on the operation of the municipal streets.
