| Abstract: | In order to achieve smooth transition between the proposed Hong Kong-Zhuhai-Macao Bridge and the tunnel,we set up an east and west artificial islands in the sea for tunnel construction.The upper part of the foundation soil of artificial island is thick silt and silt clay with sand layer,the lower is sand with pressure water,and the largest excavation depth of the foundation pit is 15.5m.To achieve the purpose of dry-land and safe construction of foundation excavation,comprehensively considering supporting s... |
