ANSYS在h形抗滑桩设计中的应用

针对滑坡剩余下滑力较大的特点,设计了h型抗滑桩。基于ANSYS有限元程序,采用BEAM3单元建立数值分析模型,对抗滑桩的受力状态进行数值分析。对抗滑桩的受力边界条件做出了合理假定,计算结果快速、简明地揭示了h型抗滑桩在滑坡剩余下滑推力下的受力特征。h型抗滑桩将作用于主桩的载荷分解、部分传递至横梁与副桩,有效承担了巨大的滑坡剩余下滑力。

Application of ANSYS on the Design of h Form Anti-slide Pile

According to the large rest push of slide,a type of anti-slide pile is schemed out,which shape is same as h.Based on the finite element program of ANSYS,a numerical analysis is taken on the stresss state of the pile,by the model of numerical analysis.And the model is set up by the element of BEAM3.It makes an reasonable assumption on the boundary conditions of the anti-slide pile.The calculation results show the stress characteristics of the h form anti-slide pile,and the pile is loaded by the rest push.The h form anti-slide pile decomposes the load which acts on the mail pile,and partly transmits it to the beam and the vice-pile.By this way,the h form anti-slide pile can bear large rest push of the slide.
