某隧道地表塌陷治理及效果评价

为确切反映隧道施工塌陷地表稳定情况及塌陷治理效果,需对隧道上部地表及邻近建（构）筑物进行监测与分析。结合某隧道的水文、地质情况,地表塌陷事故发生后采取治理措施及监控量测成果,分析该施工隧道发生塌陷主要因为地形条件、复杂的水文与地质条件、降雨影响、施工工艺。最后,结合监测结果综合采取塌陷治理措施,实现良好地治理效果。

Construction of A Tunnel Control and Effect Evaluation of Surface Subsidence

To accurately reflect the stability of tunnel construction collapse and the collapse of surface treatment effect, we need to monitor and analyze？surface of the tunnel and adjacent building （structure） building materials . The construction of a tunnel with hydrology, geology, surface subsidence control measures taken after the accident and monitoring of measurement results . Analysis of the construction of the tunnel collapse occurred mainly due to： terrain conditions, the complex hydrological and geological conditions, rainfall, construction techniques. Finally, the combined results of monitoring a combination of subsidence control measures to achieve good control effect.
