本文着重介绍日本青函隧道运营以来所进行的早期调查和今后的研究课题,调查内容包括:正洞净空断面测定;作业坑道、超前导坑的断面测定;涌水量测定和涌水的化学分析;喷混凝土的特性试验及其它追踪调查等。采用了一系列测试手段,如地震自动报警装置,衬砌应变和涌水量探测装置以及三维断面量测系统。并指出今后应重点进行调查分析和开发新的维修方法及防水材料。
This article focuses on the early investigations carried out since the operation of the Qing’kang Tunnel in Japan and its future research topics. The survey includes the following: measuring the clean section of the main tunnel; sectioning of the tunnel, leading pit; chemical analysis of water inflow and gushing water; The characteristics of testing and other follow-up investigations. A series of testing methods are used, such as automatic earthquake alarm device, lining strain and water inflow detection device and 3D cross-section measuring system. And pointed out that in the future should focus on the investigation and analysis and development of new maintenance methods and waterproof materials.
