Application of Horizontal Tension Anchor Pile on Ground in Excavation Engineering

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.
