摘要
建立了PTC管桩的荷载传递模型,并对相关参数的选取与计算进行了探讨。采用VC++语言编写了用位移协调法计算此桩在上拔荷载作用下的P-S曲线及轴力的程序,计算值与实测值吻合良好,则表明此方法合理可行,在实际工程中可用来推算管桩的极限承载力,以达到替代或部分替代现场试验的目的。
In this paper,the load transferring model of PTC pipe pile was established,selection and calculation of its parameters was discussed.According to themethod of coordination harmony displacement,the simulating calculation of P-s curves and axial force of PTC pipe piles was figured out by use of VC++language.The calculated P-S curves was conform to test results,therefore,this method is practical and feasible,In the practical projects,the existing testing information can be used to calculate P-s curve and ultimate bearing capacity of pipe piles,and this has realistic significant for replace or partially replace the in-situ load test.
