Numerical Analysis on Mechanical and Deformation Characteristics of Pile-Anchor Retaining Structure for Waterway Excavation
Abstract:
Mechanical and deformation characteristics of pile-anchor retaining structure was analyzed by using numerical simulation method. The rationality of numerical model was also verified through comparing measured data in field test and numerical results. On the basis of this numerical model, Mechanical and deformation characteristics of pile-anchor retaining structure under three different construction procedures were analyzed individually. The results show that: the maximum horizontal displacement of pile is controlled effectively by applying anchoring force, and the global horizontal displacement of pile increases as well. Forced state of pile is changed from being bended on one side to being bended on both sides, and maximum moment value decreases heavily. Therefore, anchor cable reinforcement should be arranged at the head of construction procedure of pile-anchor retaining structure. The later anchoring force be applied, the closer inflection point nears the pile top.
