Safety diagnosis of TBM for tunnel excavation and its effect on engineering

Abstract

Since the development of tunnel construction technology, different tunnel excavation technologies have also been derived for different conditions. The safety diagnosis before the TBM mining method is particularly important. With the technology of safety diagnosis, the excavation process has the following effects on the tunnel engineering work. Great guarantee. The purpose of this paper is to study the excavation process of tunnel machinery for safety diagnosis before mining by TBM. It mainly includes step excavation method, full-section excavation method, guide pit excavation method and other technologies. This article uses a city subway construction project as an example to discuss in-depth the study of tunnel machinery excavation technology before the safety diagnosis of the mining method. The specific project is a city subway line with a total length of about 25.464 km and a total of 22 stations, including 9 transfer station. Based on field engineering experiments, the problems encountered in tunnel mechanical excavation are studied. The experimental data show that the results obtained through engineering tests can guarantee the safe and stable construction of the tunnel project, and the safety rate can reach 90%. The experimental results show that the obtained results can ensure the safety of tunnel mechanical excavation.
