摘要:

基于平面应变问题,采用Druck-Prager屈服准则,研究不同地表倾角对偏压连拱隧道不同施工方法的施工力学性能的影响.通过对隧道二次衬砌力学特性及中隔墙受力分析,确定其较优的施工方法.模拟结果表明:地面倾角为5°～15°时,宜先开挖埋深较小一侧;地面倾角为15°～30°时,若能确保中隔墙稳定,则宜先开挖埋深较小一侧;反之,宜先开挖埋深较大一侧;先开挖洞室的墙脚安全系数较小,在施工中应注意加强.

Abstract:

Based on the plane strain problem, the Druck-Prager yield criterion was used to study the influence of different surface inclination angles on the construction mechanical properties of different construction methods of biased continuous arch tunnels. Through the analysis of the mechanical characteristics of the secondary lining of the tunnel and the force of the middle partition wall, the optimal construction method was determined. The simulation results show that when the ground inclination angle is 5°~15°, it is advisable to excavate the side with a small burial depth first. When the inclination angle of the ground is 15°~30°, if the stability of the middle partition wall can be ensured, it is advisable to excavate the side with a smaller burial depth first; On the contrary, it is advisable to excavate the side with a larger burial depth first; The safety factor of the wall foot of the first excavation cave chamber is small, and attention should be paid to strengthening it during construction.
