Anti-sidesway foundation of deep soft soil tunnel and construction method of anti-sidesway foundation
The invention provides an anti-sidesway foundation for a deep soft soil tunnel and a construction method of the anti-sidesway foundation. The foundation comprises a shield tunnel and a plurality of bearing structures arranged in the length direction of the shield tunnel at intervals. The shield tunnel is embedded in the gravel grouting foundation or the rock stratum foundation. And the shield tunnel is covered with a soil body filling layer. Each bearing structure comprises a bearing plate and a plurality of lower pile foundations. The bearing structure is an upper concave arc plate. And the shield tunnel is erected on the bearing structure. A gap exists between the bearing plate and the shield tunnel. The upper end of the lower pile foundation is connected with the bearing plate, and the lower end of the lower pile foundation is anchored into a gravel grouting foundation or a rock stratum foundation. The lower pile foundations in the same group are arranged at intervals in the direction perpendicular to the length direction of the shield tunnel. The tunnel anti-sidesway foundation under the deep soft soil condition can enhance the stability of a tunnel structure and reduce the risk of sidesway, so that the safety of a project is improved. The tunnel anti-sidesway foundation under the deep soft soil condition can effectively improve the tunnel anti-sidesway capacity, the service life of a tunnel can be prolonged, the maintenance and repair cost is reduced, and the sustainability of a project is improved.
发明提供一种深厚软土隧道抗侧移基础及其施工方法。该基础包括盾构隧道，以及沿盾构隧道的长度方向间隔布置的若干承托结构。所述盾构隧道埋置在砂石灌浆基础或岩层基础中。所述盾构隧道上方覆盖有土体填层。每组承托结构包括承托板和若干下部桩基础。所述承托结构为一块上凹圆弧板。所述盾构隧道搭设在承托结构上。所述承托板与盾构隧道之间存在间隙。所述下部桩基础的上端与承托板连接，下端锚固入砂石灌浆基础或岩层基础中。同一组下部桩基础沿着与盾构隧道长度方向垂直的方向间隔布置。深厚软土条件下隧道抗侧移基础可以增强隧道结构的稳定性，减少侧移发生的风险，从而提高工程的安全性。深厚软土条件下隧道抗侧移基础能有效提高隧道抗侧移能力，有助于延长隧道的寿命，减少维护和修复成本，提高工程的可持续性。
