To address the challenges of predicting the interaction effects of ground displacement and mitigating surface subsidence risks in double-line parallel shield tunneling, this study proposes a three-dimensional analytical method for displacement in unsaturated soil. Based on the initial solution for unsaturated soil under buried-depth loading, a three-dimensional analytical solution for ground displacement induced by double-line parallel shield tunneling is derived using the superposition principle, while comprehensively accounting for multiple influencing factors such as construction loads and soil loss. The validity and reliability of the proposed solution are verified through comparisons with real-world engineering cases. The results indicate that the longitudinal distance between tunnels and the transverse spacing of their axes significantly influence soil displacement: reducing the longitudinal spacing from 120 m to 0 m increases the peak total surface subsidence from 6.08 mm to 9.10 mm (a 50.0% increase); decreasing the transverse axis spacing from 1D to 9D reduces horizontal ground displacement by 49.2%; and lowering the depth-to-diameter ratio Z/D from 3 to 1 causes the peak subsidence to surge from 15.9 mm to 49.4 mm (a 210.7% increase), resulting in a deeper and narrower settlement trough. The study highlights that rational control of the longitudinal spacing of excavation faces, transverse axis spacing, and depth-to-diameter ratio is key to reducing surface subsidence risks during double-line parallel shield tunneling. The proposed analytical method offers a theoretical basis for optimizing construction parameters and mitigating subsidence risks.

为解决非饱和黏土中双线平行盾构施工引起的地层位移相互作用效应难以预测、易引发地表沉降风险的问题,本研究提出一种针对非饱和土三维位移解析方法。基于非饱和半空间初值解,并采用叠加原理推导出双线平行盾构施工引起的地表位移三维解答,同时充分考虑各施工荷载和土体损失等多种影响因素。通过与实际工程案例结果对比,验证了本文解析解的有效性和合理性。结果表明:双线盾构的纵向距离和轴线横向距离对其引起土体位移有显著影响;当双线纵向间距从120 m缩小至0 m,地表总沉降峰值从6.08 mm增至9.10 mm,增幅50.0%。双线隧道轴线间距从1D增至9D,地表水平位移降幅达49.2%;埋深比Z/D从3降至1,沉降峰值从15.9 mm激增至49.4 mm,增幅210.7%,使得地表沉降槽更深、更窄。研究表明,在双线平行盾构施工过程中,合理控制开挖面纵向距离、盾构轴线间距和埋深比是降低地表沉降风险的关键措施。本文方法可为双线盾构施工参数优化与沉降风险防控提供理论依据。

为解决非饱和黏土中双线平行盾构施工引起的地层位移相互作用效应难以预测、易引发地表沉降风险的问题,本研究提出一种针对非饱和土三维位移解析方法。基于非饱和半空间初值解,并采用叠加原理推导出双线平行盾构施工引起的地表位移三维解答,同时充分考虑各施工荷载和土体损失等多种影响因素。通过与实际工程案例结果对比,验证了本文解析解的有效性和合理性。结果表明:双线盾构的纵向距离和轴线横向距离对其引起土体位移有显著影响;当双线纵向间距从120 m缩小至0 m,地表总沉降峰值从6.08 mm增至9.10 mm,增幅50.0%。双线隧道轴线间距从1D增至9D,地表水平位移降幅达49.2%;埋深比Z/D从3降至1,沉降峰值从15.9 mm激增至49.4 mm,增幅210.7%,使得地表沉降槽更深、更窄。研究表明,在双线平行盾构施工过程中,合理控制开挖面纵向距离、盾构轴线间距和埋深比是降低地表沉降风险的关键措施。本文方法可为双线盾构施工参数优化与沉降风险防控提供理论依据。

To address the challenges of predicting the interaction effects of ground displacement and mitigating surface subsidence risks in double-line parallel shield tunneling, this study proposes a three-dimensional analytical method for displacement in unsaturated soil. Based on the initial solution for unsaturated soil under buried-depth loading, a three-dimensional analytical solution for ground displacement induced by double-line parallel shield tunneling is derived using the superposition principle, while comprehensively accounting for multiple influencing factors such as construction loads and soil loss. The validity and reliability of the proposed solution are verified through comparisons with real-world engineering cases. The results indicate that the longitudinal distance between tunnels and the transverse spacing of their axes significantly influence soil displacement: reducing the longitudinal spacing from 120 m to 0 m increases the peak total surface subsidence from 6.08 mm to 9.10 mm (a 50.0% increase); decreasing the transverse axis spacing from 1D to 9D reduces horizontal ground displacement by 49.2%; and lowering the depth-to-diameter ratio Z/D from 3 to 1 causes the peak subsidence to surge from 15.9 mm to 49.4 mm (a 210.7% increase), resulting in a deeper and narrower settlement trough. The study highlights that rational control of the longitudinal spacing of excavation faces, transverse axis spacing, and depth-to-diameter ratio is key to reducing surface subsidence risks during double-line parallel shield tunneling. The proposed analytical method offers a theoretical basis for optimizing construction parameters and mitigating subsidence risks.
