摘要

常规的弹性解无法对具有强蠕变特性的软岩隧道变形规律提出合理解释.因此,针对软岩隧道施工的时间-空间效应,引入Burgers模型揭示其时空演化规律,并通过数值计算探究不同因素对黏弹性围岩纵向变形规律的影响.同时基于响应面法得到位移释放系数的经验公式,与现场监测和其他理论比较验证了本文方法的可行性.研究结果表明地应力对位移释放系数影响可忽略,Kelvin切变模量、Kelvin黏滞系数、Maxwell切变模量和开挖速度显著影响位移释放系数,而根据延滞时间的不同可分为低延滞系数、中延滞系数和高延滞系数3类;针对时间效应影响型、空间效应影响型和时空效应影响型3种黏弹性围岩纵向变形曲线类型拟合得到相应的经验公式.研究结论可为软岩隧道变形预测提供更简便的方法.

Abstract

Conventional elastic solutions cannot explain the deformation characteristics of soft rock tunnels exhibiting creep behavior. Therefore, a Burgers model is introduced to demonstrate the space-time effects in the construction period of soft rock tunnel. The influences of different factors on the longitudinal deformation behavior of viscoelastic rock as well as the spatiotemporal evolution patterns have been revealed through numerical simulations. An empirical formula for the displacement release coefficient is derived using the response surface method. The feasibility of the proposed method is validated by comparing the results with on-site monitoring data and other theoretical values. The findings indicate that geostress has a negligible effect on the displacement release coefficient. In constrast, the Kelvin shear modulus, viscosity coefficient, Maxwell shear modulus, and excavation speed significantly affect the displacement release coefficient. According to viscosity time, the hysteresis coefficient can be divided into three categories: low, medium, and high. Empirical formulas are fitted for the longitudinal deformation curve, including time, spatial, and spatiotemporal factors. The research conclusion can provide a more convenient method for predicting the deformation of soft rock tunnels.

Key words： viscoelasticity; longitudinal deformation profile; soft rock tunnel; time-space effect; displacement release coefficient
