The Study Of Soil Arching Effects Of Sheet-pile Wall And Optimization Design

Pile board structure is a new common slope reinforcement structure emerged in recent years,with good protection and strengthening effect,pile plate structure is composed of anti-slide pile and baffle wall structures by stabilizing piles evolved,it is widely used,it can be used for special land area,high slope and embankment seismic area and rain prone areas,cutting.In the Slope is more common application means.This paper studies the interaction mechanism between the pile and the rock mass between board structure and board structure analysis of pile embedded depth of optimization.Research paper pile board structure has the following main content(1)pile plate structure embedded pile Solid mode.Analysis of pile were free,hinged,fixed three states moment and displacement of different variations in order to find a reasonable embedded solid condition.(2)based on soil arching theory to study the pile board-Mechanism of rock and soil interactions."Platts unloaded arch" theory,the force between the plates pile of rock and soil model by ANSYS numerical analysis taking into account the interaction between the pile and the soil under static and seismic action,drawn from the pile between the plates is reduced according to;internal friction angle of rock and soil increases,cohesive force increases,soil arching effect more obvious.(3)established by FLAC 3D Pile-plank retaining landslide model,numerical simulation baffle plate structure internal force of pile when the pile around,can better play the role of stabilizing the landslide analysis results when the front bezel.(4)pile embedded solid depth on landslide stability,take the pile embedded solid segment length parameter as variables to analyze the pile of maximum displacement and the stress FLAC 3D numerical simulation are adopted,so as to arrive when embeded pile length of 1 / 2-1 / 3 of the total length of the pile is most reasonable.(5)Equivalent Beam Method pile embedded depth thus proving the reliability of conclusions,and then calculated based on the above studies optimized a simple,consistent engineering pile embedded depth approach.
