Abstract


Anchor anti-slide pile system already used in engineering practice , but because of the complexity and uncertainty of their hosting environment ( rock and soil ) , so that the existing design methods with a large empirical . Bolt anti-slide pile model tests based on homogeneous soil slope , through qualitative analysis and quantitative calculated combining the bolt anti-slide pile design theory . This paper mainly work in the following areas : (1) analysis of anchor anti-slide pile system project and a number of problems in the design , and describes the existing pile - anchor system design theory . ( 2 ) on the basis of analysis of model test of anchor anti-slide pile for homogeneous soil slope , come to anchor anti-slide pile four possible force distribution schema . Stress analysis of the basis of the following model pile slip surface anchoring depth of the bolt anti-slide pile model in normal working condition reasonable ; pointed out that the range of values ??of the force , that is, between non- cohesive soils with passive earth pressure of cohesive soil values ??. ( 3) on the basis of the analysis of model test for homogeneous soil slope , respectively elasticity with the slip line method for solving anchor anti-slide pile anchorage depth research . The analysts believe that the elasticity law due to the limitations of its assumptions , only draw pile is in normal working condition , stress and deformation is very small in the Soil Caused point ; slip line method for soil in the ultimate bomb the plastic failure of a numerical solution , and therefore I believe that the the anchoring depth values ??derived this way have a certain reference value for homogeneous soil slope . ( 4 ) through the analysis of the results obtained with similar model test comparison that the pressure distribution law author did anchor anti-slide pile test literature as well as the location of the maximum pressure in the slip below are relatively close , thus further verify the conclusions drawn by the author .
