IN-SITU TESTING STUDY ON LINING SYSTEM OF DOUBLE-ARCHED TUNNEL
双连拱隧道支护体系现场监测试验研究

The variation of stress and deformation in tunnel lining system is the direct indication of its safety. Systematic in-situ testing scheme is established for Jinzhuling double-arched tunnel. The testing results of stress in the lining system and displacement in the vault are analyzed in detail,and some suggestions are given for the design and construction of double-arched tunnel.
