| 摘 要： | 山东海化纯碱厂石灰石货运地仓基坑工程分二期施工，因场地地层松软、周边环境变形要求严格，须采用桩锚支护；为避免土层锚杆成孔困难和充分利用二期基坑的护坡桩作一期基坑的锚桩以降低工程造价，设计采用了地面水平拉锚桩支护结构体系。经实践检验，效果良好。详细介绍了该支护结构体系的设计、验算和施工过程，以及监测效果。

| Abstract: | An excavation engineering was divided into 2 stages, pile-anchor reinforcement was necessary for the environment of soft ground and strict requirement for surrounding deformation. In order to avoid the anchoring hole-forming difficulty and make full use of slope protection-pile of 2 - stage excavation to be the 1 - stage anchor pile for lowering the engineering cost, the design was made by excavation sturcture of pile with horizontal tension anchor on ground, which was proved with good result. The paper introduced the design, checking; construction process and the monitoring effect. |
