摘要:
近年来,随着壁板桩的广泛应用,相关研究逐步展开,但水平承载特性的研究成果仅限于现场试验和弹性理论定性分析,且两者所得结果差距比较大。在香港科技大学所做的壁板桩静载试验基础上,使用ABAQUS有限元软件分析壁板桩水平承载特性,并与Zhang的数值模拟计算结果进行比较,试验数据与计算数据非常接近,相差在5%以内,验证了ABAQUS模拟壁板桩水平受荷的可行性。在此基础上分析桩顶位移、桩身弯矩在加载-卸载循环下的变化规律,进一步考虑荷载作用对壁板桩截面的非线性影响,作用力夹角α和位移夹角β相关,当荷载作用方向α=45°时,荷载与位移方向的夹角最大;x、y方向桩身最大弯矩随荷载作用角度变化而变化,α < 45°,x方向的弯矩能得到有效传递,α > 45°时,y方向的弯矩传递深度加深有限。分析结果有利于对壁板桩水平承载特性的理解,有利于现场试验数据与弹性理论计算结果相结合。
Abstract:
Recently,with barrette foundations widely used,many researchers have been carrying out on the behavior of lateral loaded.However,at present,almost all the researches are limited to field experiment and elastic-theory analysis,the results with the two methods can not coordinate with each other.Using ABAQUS to analyse lateral-loaded barrette based on the static-loaded test of The Hong Kong University of Science and Technology,The simulation results are compared with the value of Zhang to verify the feasibility of the lateral-loaded barrette.Further we consider the nonlinear effect of the load direction on the pile section,When α=45°,included angle|β-α|of the load and displacement got the maximum result.The maximum bending moment of pile in the direction of x and y varies with the angle of load.When α < 45°,the bending moment of x direction can be effectively transmitted,When α > 45°,the bending moment of Y direction can be Limited transferred to the depth.To investigate the characteristics of lateral loaded barrettes and to set a bridge on the gap of the results mentioned will have a great meaning for the research in the future. β-α
