摘要/Abstract

摘要： 盾构隧道受周围施工环境影响，易产生不均匀沉降、局部隆起、水平偏位及收敛变形等结构变形问题，常采用注浆的方式对隧道进行主动控制。按照盾构隧道易发生的结构变形，对现有注浆治理服役期盾构隧道结构变形的方法进行全面总结，将现有注浆治理方法分为隧道偏位治理与收敛变形治理2个方面，其中,隧道偏位治理分为隧道竖向的沉降、隆起治理与水平向偏位治理；收敛变形治理分为隧道常见的横椭圆与竖椭圆变形治理，进一步根据注浆地点与隧道的位置关系分为隧道内注浆和隧道外注浆。此外，对不同结构变形的治理机理进行分析，根据理论解析、数值模拟、工程实例分析、模型试验4种研究方法对研究现状及施工建议进行总结。针对现有问题，从沉降变形治理、隆起变形治理、水平偏位治理、横椭圆变形治理、竖椭圆变形治理、治理效果、注浆工艺7个方面提出若干解决建议及后续的研究方向选择。

Abstract: Shield tunnels are susceptible to structural deformation issues such as uneven settlement, local uplift, horizontal deviation, and convergence deformation due to the influence of surrounding construction environment. Grouting is often used to actively control these problems. The authors provide a comprehensive summary of the existing methods for grouting treatment of deformation in shield tunnels during service life. According to the structural deformation that shield tunnels are prone to, the existing grouting treatment methods are divided into two aspects: tunnel deviation treatment and convergence deformation treatment. Tunnel deviation treatment is divided into vertical settlement, uplift, and horizontal deviation treatment, while convergence deformation treatment is divided into common horizontal and vertical elliptical deformation treatment in tunnels. Furthermore, according to the relationship between the grouting location and the tunnel position, it is further divided into grouting inside the tunnel and grouting outside the tunnel. In addition, the authors analyze the governance mechanisms of different structural deformations, and summarize the research status and construction suggestions based on four research methods: theoretical analysis, numerical simulation, engineering case analysis, and model testing. In response to existing problems, several solutions and future research directions are proposed from seven aspects: settlement deformation treatment, uplift deformation treatment, horizontal deviation treatment, horizontal elliptical deformation treatment, vertical elliptical deformation treatment, treatment effect, and grouting technology.
