支护措施对浅埋隧道性状和地表沉降的影响

Effects of Reinforcement on Behaviour of Shallow Tunnel and Settlement of Ground Surface

隧道开挖将引起地层变形和地表沉降,过大的沉降将影响地上结构物的安全。本文采用数值方法分析支护措施对浅埋隧道性状和地表沉降的影响,通过组合不同的支护类型和设置不同的支护参数进行参数分析,研究地表的沉降规律,为有效控制地表沉降提供理论参考。

Excavation of tunnel will lead to the deformation of stratum and the settlement of ground surface. The excessive settlement willl influence the safety of constructions on the ground. This paper employs the numerical method to analyse the effects of reinforcements on the behaviour of shallow tunnnel and the settlement of ground surface. Through combining different reinforcement types and setting different reinforcement parameters , the parameter analysis is performed to study the law of the ground surface settlement and to provide the theoretical reference for controlling the ground surface settlement effectively.
