| Abstract: | The foundation support of car damper in Huaneng Yingkou Powerplant is difficult to construct,because it is less than 1 kilometer from embankment of Bohai,and the silt layer is very thick. The deep foundation excavation is supported with bored piles and soil nailing wall. The bored piles combining with cables and beams act as main bearing members. Reinforced mesh and shotcrete are set among anchors to form soil nailing wall. The monitoring results show that the foundation slope is stable and deformation of s... |
