摘要
新意法是基于围岩的压力拱理论和新奥法施工理论提出来的,是通过对岩体分类来确定超前支护措施和支护参数的设计方法,其核心思想是通过调节超前核心土的强度和刚度来控制岩体的变形。该方法在欧洲一些国家的大型隧道中广泛采用,在我国仍处在探索使用阶段。在新意法核心思想的基础之上,对几种新意法预约束施工技术如全断面机械预切槽技术、预切成洞衬砌技术、旋喷注浆管棚技术、蜂窝状拱衬砌技术等进行了论述。
ADECO-RS is proposed based on rock pressure arch theory and New Austrian Method.It determines the advanced supporting measures and support parameters by classification of rock mass.Its core idea is that the deformation of rock mass could be controlled by adjusting the core soil strength and stiffness.This method has been widely used in large tunnels in European countries.While in China,it is still in the exploration phase.Some pre-constraint construction measures using ADECO-RS such as the full-section mechanical pre-cutting technology,pre-cut tunnel lining technology,jet grouting technology,and cellular arch lining technology are elaborated in this paper.This work provides reference for the application of ADECO-RS in tunnel engineering in China.
