Effects and Regularity of Different Slit & Bar Design on TFT Characteristics

3D Simulation of Tunnel Collapse Consolidation and <i>In Situ</i> Monitoring Analysis

“…The collapse length is 17m and its collapse height is 73m. There is a flared bell-like subsidence hole occurred and its deepest depth is 12m, catchy diameter is 26m, the amount of collapse is 1700m 3 . At present, the tunnel collapse is most common in tunnel construction and relatively typical accident, has become an important safe hidden trouble causing time delay, losses of lives and property and tunnel operation [1][2] .…”

“…Engineering practice shows that the forms of tunnel collapses are different under different conditions because of different influence factors. Geological conditions, design, construction technique and management factor are generally considered to be the main factors of influence tunnel collapse [2][3][4] . There are many engineering examples [5][6] of collapse consolidation at domestic and abroad, but the majority is based on experience.…”
