| Abstract: | Through the analysis of the causes of the collapse in the shallow-covered,bias pressured outlet section of the Pingyang Tunnel of the Xiang-Yu Expressway,determined are some rational comprehensive collapse-treating technical plans,such as sealing the gaps,properly clearing spoil,stabilizing the collapsing bodies by means of slip-casting concrete,lengthening the open-cut cave and refilling to increase the inverted pressure,speeding up the construction of the construction shafts,and stabilizing the section be... |
