| Abstract: | High pressure water-soaked cavity at DK245+260 of Yunwushan tunnel on Yichang-Wanzhou railway is approximately 13.28 m long and 31.2 m wide filled with clay and sand. According to the construction record, the highest water pressure exceeded 0.56 MPa and the maximum water inflow was 1 100 m3/h. Geological disasters of water and sand inrush often happened during the constructions. M10 mortar was used to backfill the water -soaked cavity and full -face curtain grouting was adopted. In this way, the water -soak... |
