摘要：

为了研究隧道硬石膏围岩膨胀作用下的位移变化规律，基于湿度应力理论，考虑硬石膏膨胀性的时变特征，建立含时间效应的隧道弹-膨胀解析模型.将模型应用于梁忠高速礼让隧道，获得隧道临空面位移变化规律的定量结果，隧道围岩响应曲面以及位移特性曲面.对模型各参数进行敏感性分析，结果表明：1）围岩岩性越好，临空面位移越小，隧道结构越稳定，结果与实际规律相一致；2）隧道临空面位移与隧道支护应力、围岩弹性模量呈负相关，与隧道洞径、静水压力、吸水率、围岩膨胀模量、膨胀时间、吸水系数及线膨胀系数呈正相关.
Abstract:

The elastic-swelling analytic model considering time effect of tunnel through anhydrite rock mass was established based on the humidity stress field theory and the time dependence of anhydrite in order to analyze the tunnel displacement variation rule under the swelling of anhydrite rock. The model was applied to the Lirang Tunnel on Liangzhong highway. Then the quantitative analysis of the displacement variation rule of free face, the ground reaction surface and displacement characteristic surface were obtained. Then the sensitivity analysis of the model parameters was conducted. 1) The better of the surrounding rock, the smaller displacement of the free face, thus the tunnel structure is more stable The result accorded well with the practice rule. 2) The displacement of the free face was negatively correlated with the tunnel supporting stress and the elastic modulus of surrounding rock, and was positivly correlated with the tunnel hole diameter, the hydrostatic pressure, the water absorption, the rock swelling modulus, the swelling time, the water absorption coefficient, and the linear swelling coefficient.
