Visual Display of Tunnel Water Damage in Construction Stage

Research purpose: the tunnel often suffers from water disaster during the construction stage under the influence of various factors,, and the Water inflow can reflect the threat to the tunnel to a certain extent. At the same time, the impact of water damage on the tunnel has a long-term nature, and its occurrence location is a sensitive part of the operation stage, which must be monitored later. However, the water hazard information record in the construction phase is generally paper-based, and the archive information data is too much and not intuitive. Therefore, it is necessary to visualize the archive data. In this paper, BIM Technology is used to locate and visualize the water inflow of the tunnel, so as to facilitate the maintenance during the operation period. The conclusions are as follows: (1) Based on the established 3D solid tunnel model, the program to determine the specific location of water damage on the tunnel cross section is compiled. (2) RGB color can give different warning to the observer, reflecting the feasibility of tunnel water output in the construction stage. (3) The research results can provide a reference for the visual display of information files of disease problems in tunnel construction stage.
