h型斜横梁支座式抗滑桩计算模型及力学性能研究
Study on calculation model and mechanical properties of h-shaped inclined beam bearing anti-slide pile
摘要
Abstract
To solve the problem of brittle failure at the rigid connection of the traditional h-shaped anti-slide pile beam,a structural optimization scheme was proposed,which simplified the multi-time super-static structure into an inclined"simply supported"structure and proposed the h-shaped inclined beam bearing anti-slide pile.Based on the Winkler elastic foundation beam theory and the structural force degree shift method,the analytical model was established by using the numerical analysis and numerical simulation methods.The results show that the theoretical calculation of the analytical solution is in good agreement with numerical simulation results,which proves the rationality of the calculation model.Compared with the traditional h-shaped pile,the optimized structure has significant advantages,that is,the bending moment at the connection between the rear pile and the beam is greatly reduced,the bending moment at the top of the pile of the front pile is completely released(the reduction is 0),the shear force of the beam is significantly reduced,and the stress concentration phenomenon at the connection is avoided.From the analysis of key geometric parameters,it can be seen that with the increase of the angle of the oblique beam,the internal force and deformation of the oblique beam and the rear pile decrease,and with the increase of the distance between the front and rear piles,the internal force and deformation of the front pile decrease,and the mechanical performance of the system is better.关键词
