摘要
随着工程技术的发展,超高强混凝土在工程中的应用越来越广泛。然而超高强混凝土预应力管桩在国内的应用仍是空白。该文利用大型通用有限元软件ABAQUS对高强混凝土预应力管桩的抗剪承载力进行了深入的研究,并系统地研究了剪跨比和混凝土强度对预应力管桩抗剪承载力的影响。结果表明,剪跨比对抗剪承载力影响较大,提高混凝土强度可以提高管桩的抗剪承载力。
With the development of engineering technology,ultra-high strength concrete in the application of more and more widely.However,the application of super high strength concrete prestressed pipe pile in the country is still blank. In this paper,the shear capacity of high-strength concrete prestressed concrete piles is studied by using ABAQUS large-scale general finite element software,and the influence of shear span ratio and concrete strength on shear capacity of prestressed concrete piles is systematically studied.The results show that the shear span ratio has a great influence on shear bearing capacity and improving of the strength of concrete can increase the shear bearing capacity of pile.
