  A novel clustering classification method of surrounding rock mass for TBM tunnel

  Abstract: Accurate classification of surrounding rock mass can identify the geological conditions in front of the tunnel face in time, and effectively guide the optimization of TBM tunneling parameters and the design of support schemes. According to on-site tunneling data from the 3rd TBM section of Songhua River water supply project in Jilin province, this paper first extracts the rock mass excavability...

  Solving Tunnel External Loads Based on Betti’s Reciprocal Theorem

  Abstract: Soft ground tunnels are vulnerable to a variety of defects during operation. With rapid development of urban rail systems worldwide, especially in China, tunnel structural health assessment has brought extensive attention. Surrounded by soils and groundwater, tunnels are different from bridges, buildings, roadways and other above-ground structures due to the uncertainties associated with the...
