摘要: 本文作者把围岩应变法、孔洞位移法和衬砌内力法三种地下结构设计模型与圆形隧道的弹、塑、粘性三种衬砌计算理论结合起来,通过室内的模型试验和现场量测验证后,得到了地层压力与衬砌刚度以及地层本构关系有关的设计公式;得出了侧压力系数随衬砌与地层的刚度比而变化,且比静止侧压力系数大。将此法运用于新奥法或盾构法隧道设计中,即可减薄衬砌,节省投资。Abstract: In this paper three design models of underground structure proposed by the author, i. e. rock strain model, opening displacement model and internal force of lining model are combined with three calculation theories of elasticity, plasticity and viscosity for circular lining. The design formulae of ground pressure related to the lining stiffness and constitutive law of surrounding ground are obtained, they are also checked by the laboratory test of simulation material and field measurement. The coefficient of lateral pressure varies with the stiffness ratio between lining and ground, it being larger than the coefficient at rest. The lining will be thiner and cheaper when the method in this paper is used to design tunnels especially by the New Austrian Tunnel Method and the Shield Method.
