The Field Test And Numerical Simulation Of Pre-stress Anchorage Cable

This thesis is base on analyzing and contrasting the calculation method ofpre-stress anchorage cable and constructs the model of analysis of anchoragecable. It studies the calculation method of pre-stress anchorage cable, thepassing rule of the stress within the anchor block on the different terrenes andvalid length. It draws a lot of meaningful conclusions.To make clear what the mechanism and status of mechanics in the soilmedium of anchorage cable cable, the field research of anchorage cable havebeen provided. It includes the testing on the carrying capacity of anchoragecable in saturated soft soil. It gets the P～S curve lines which providesfoundation for further research.Compare with finite element method and boundary element method, theLagrangian method show much more advantages on solving the distortion ofrock mechanics. This thesis discusses the basic theory of Lagrangian methodas well as the method and peculiarity in setting up anchorage cablemechanical model with FLAC^3D(Fast Lagrangian Analysis Continue). Thedrawing test has been built up. It shows that the results of the test are wellwith the calculation. On the base of the above theory, numerical simulatecalculation has been made. It also studies on the reinforcement mechanismand the passing rule of pre-stress of anchorage cable.This thesis builds up the Haihe River bank's three-dimensional nonlinearnumerical analyzed model including the co-working of soil body, plank picketand anchorage cable. It analyzes the reinforcement effect by the bank's initialstress, the mechanism the pre-stress anchorage cable and the stress field underthe effect of the initial stress and the pre-stress of anchorage cable. This thesisprovides new view on the reinforcement mechanism of pre-stress anchoragecable.
