摘要
新意法作为继新奥法之后兴起的一种隧道修建理念,为解决软弱围岩等复杂条件下新奥法无法施工或很难施工的技术难题提供了新的解决途径,具有可全断面机械开挖、安全质量风险可控等优点。文章介绍了新意法的核心理论思想,并结合在国外实施的甘塔斯隧道工程实例,阐述了新意法理念独特的技术优势和应用前景。
As a new tunnel construction concept after NATM,ADECO-RS provides a new solution for the technical problems that NATM can not be implemented or the construction is difficult under weak sur-rounding rock and other complex conditions,which has the advantages such as full-section mechanical excavation,and controllable safety and quality risks.This article introduced the core theoretical ideas of ADECO-RS method,and combined with the Gan Tasman Tunnel project example implemented in for-eign country,it described the unique technology advantages and application prospects of ADECO-RS concept.
