摘要
随着国家山区高速公路与高速铁路建设的快速发展,新建隧道开挖诱发滑坡的地质灾害时有发生,同时既有隧道在滑坡作用下产生的病害也越来越严重,对隧道的施工和运营均造成了较大危害。为了促进高速公路与高速铁路隧道-滑坡体系研究的发展,归纳总结了国内外隧道-滑坡工程领域的学术研究现状、存在问题及发展前景。对隧道-滑坡相对位置关系及变形特征进行系统梳理;从地质调查分析、理论解析、模型试验、数值模拟和监测分析5个方面详尽剖析了隧道-滑坡相互作用影响的研究现状;从滑坡体加固、隧道加固和监控预测技术3个方面对隧道-滑坡相互作用影响的控制防护技术研究进行了全面阐述;指出现有研究中存在的不足和尚需讨论的方面,建议深入开展滑坡土体塑性、非线性接触、地震与降雨多因素耦合作用、离心模型试验的开发与利用、本构模型的适用性及隧道精细化建模等方面的研究,积极优化和创新防护控制措施技术,建立隧道-滑坡之间联动共享的新型监控成套技术体系,以期为隧道-滑坡体系工程领域的学术研究提供新的视角和基础资料。
With the rapid development of mountainous highways and high-speed railways in China, geological disasters caused by new tunnel excavation, such as landslides, are widespread. Meanwhile, the diseases caused by landslides in existing tunnels are also increasing, resulting in significant harm to the tunnel construction and operation. In this paper, the academic research status, existing problems, and the development prospects associated with the tunnel-landslide system were summarily all over the world. First, the relative spatial location relationship and deformation characteristics of the tunnel-landslide system were systematically investigated.Second, the detailed analyses of the current status and prospects of research on tunnel-landslide interaction from five aspects geological survey, theory, model test, numerical simulation and field monitoring. Then, the control and protection techniques of the tunnel-landslide interaction were expounded from landslide reinforcement, tunnel reinforcement, and monitoring and prediction technology, and the corresponding shortcomings in the existing research and the aspects that still need to be discussed were marked.Finally, it is recommended to carry out further research on the landslide soil plasticity, nonlinear contact, earthquake and rainfall multi-factor coupling effects, the development and utilization of centrifugal model tests, the applicability of constitutive models, and the fine modeling of tunnels. Also, the impact zones of tunnel excavation should be further optimized, and the corresponding novel control and protection technologies should be developed. On this basis, a new type of monitoring technology system linked and shared for tunnel-landslide can be thus established. This paper provides new perspectives and essential data for academic research on tunnel-landslide system engineering.
