The Mechanism Of Structure Research On Oblique-inserting Slab-pile Wall Of Hanging Slab

The oblique-inserting slab-pile wall is a new type slab-pile wall structure form, it can not only as a traditional slab-pile wall as retaining structures to maintain the stability of the slope soil, itself will also be able to play the role of greening. It has development based on the anti-slide pile and traditional upright slab-pile wall, it has the form such as simply supported plate type and the anchored type. The oblique-inserting slab-pile wall is lesser at this respect of the research application and engineering practice. Based on the special structural form of the retaining wall and its own greening effect, it is very necessary to research on the mechanism of structure of the oblique-inserting slab-pile wall in order to further promote the engineering application of this kind of retaining wall. It mainly discusses the mechanism of structure of the oblique-inserting slab-pile wall of hanging slab.It comprehensive analysis the mechanism of structure of other kinds of retaining wall and determine the model test method of the oblique-inserting slab-pile wall of hanging slab based on the large number of related literatures home and abroad. Based on the similar theory of model test, it selects a more appropriate model test material so as to research the influences of tilt angle of plate on the oblique-inserting slab-pile wall of hanging slab. In addition, on the basis of model test, it builds the numerical analysis model by using finite element analysis software, to conclude the results of numerical calculation and model test results which are compared so as to calculate the related conclusions of the mechanism of structure of the oblique-inserting slab-pile wall of hanging slab.By the results of numerical calculation and model test results, it can be concluded that:1) The earth pressure behind the pile is slowly increasing and reducing at the bottom of the pile cantilever depth in a nonlinear trend, whose distribution forms is similar to the normal pile, while the distribution of the earth pressure behind the plate of tilt insertion is indented; 2) The pile stress distribution characters are also similar to ordinary pile; 3) The earth pressure behind the 43 angle plate of tilt insertion is more reduced at the bottom of the pile cantilever depth and the structure stress of the plate is least by comprehensive analysis., so the angle 43 is the best value; 4) Through the comparison of numerical results with experimental results, it can conclude that the numerical results are agree with the experimental results. And it can analysis the mechanism of structure of the oblique-inserting slab-pile wall by using finite element analysis software in the condition that selecting appropriate parameters and constitutive model.
