Coupling Analysis of Seepage-Stress-Cracking for Inner Water Exosmosis of Pressure Tunnel

  • 摘要: 针对压力隧洞内水外渗分析缺乏完善的渗流-应力-开裂耦合分析模型的现状,基于传统的黏结裂缝模型,提出了能进行渗流分析的黏结裂缝单元模型.应用Biot固结理论和内水荷载施加的体力理论,建立了压力隧洞内水外渗的渗流-应力-开裂耦合分析模型.选择典型的圆形断面压力隧洞进行了内水外渗的渗流-应力-开裂耦合模拟分析.计算结果与实测资料的定性对比表明,该模型是合理可行的,可用于压力隧洞内水外渗的渗流-应力-开裂耦合分析.
    Abstract: Aimed at the lack of perfect seepage-stress-cracking coupling analysis model in simulating inner water exosmosis of pressure tunnel,a cohesive crack element model coupled with seepage analysis is introduced based on the traditional cohesive crack model.A seepage-stress-cracking coupling analysis model for inner water exosmosis of pressure tunnel is established based on the Biot's consolidation theory and the body force theory of applying the inner hydraulic pressure.A typical pressure tunnel with circular section is chosen as an numerical example to verify the coupling analysis model.The simulation results qualitatively agree well with the test results.Therefore,this coupling model is reasonable and feasible,and the model can be used to conduct coupling analysis of seepage-stress-cracking for the inner water exosmosis of pressure tunnel.
