双孔平行隧道施工地表沉降

On surface settlement of double tube tunnel excavation construction

分别采用Peck公式和随机介质理论计算双孔平行隧道施工引起的地表沉降,并结合具体工程实例确定影响地表沉降的参数取值,并对随机介质理论和Peck公式的参数进行了对比说明,从而指导现场施工。

The paper adopts Peck formula and the stochastic medium theory to calculate the surface settlement caused by the double tube tunnel excavation construction, identifies the parameter value which influences the surface settlement by combining with the factual project, and compares the parameters of the stochastic medium theory and Peck formula, so as to direct the field construction.
