摘要
针对浅薄覆盖层、倾斜岩面条件下钢护筒沉放难以自稳和锚固的问题,通过技术方案调研、比选、现场模拟和仿真计算,提出了"抱桩+跟进"的解决方案。该方案克服了桩基钢护筒在裸岩条件下沉放难以自稳和无法锚固的困难,并在富翅门大桥9号主墩桩基钢护筒施工中成功应用。
In view of the problem that the sinking of the steel cylinder is difficult to be stable and anchored under the condition of shallow over burden and inclined bare rock, through research and comparison of steel casing construction technical plan, combined with simulation calculation and on-site simulation, we adopt innovative steel casing construction technology “hold pile ＋ follow up”,which solves the problem that it＇s difficult to stabilize and anchor steel casing for pile foundation on the bare rock. The plan has been successfully applied to steel casing for pile foundation of No.9 main pier in Fuchimen Bridge.
