摘要
通过岩土专业有限元PLAXIS3D软件,选取能够反映软土真实力学特性的小应变土体本构模型,采用精细化建模方式,模拟盾构法施工中盾构机重力,土仓压力、盾尾注浆压力及盾构机推进产生的摩阻力等因素影响下,被穿越隧道的变形发展过程。
Through the finite element PLAXIS3D software for geotechnical specialty, this paper selected the small strain soil constitutive model reflecting the real mechanical characteristics of soft soil, using the fine modeling method, simulated the deformation and development process of underneath pass tunnel under the friction resistance and other influence factors of shield machine gravity, soil warehouses pressure, shield tail grouting pressure and shield machine propulsion caused.
