In order to analyze the stress state around the projecting buried pipe accurately,the pipe-soil interaction should be considered.Base on the condition of pipe-soil displacement harmony,the pipe-soil interaction boils down to a stress concentration problem of planar elastic medium embedded with an elastic circular tube in gravity field.The distribution functions of stress and displacement around pipe wall are obtained through elastic analysis,and the calculation model of the internal force of the...

In order to analyze the stress state around the projecting buried pipe accurately,the pipe-soil interaction should be considered.Base on the condition of pipe-soil displacement harmony,the pipe-soil interaction boils down to a stress concentration problem of planar elastic medium embedded with an elastic circular tube in gravity field.The distribution functions of stress and displacement around pipe wall are obtained through elastic analysis,and the calculation model of the internal force of the pipe section is simplified.Finally,a case study is carried out,and the results are compared with several other calculation formula of soil pressure in buried pipe.

为准确分析埋地管道的管周应力状态,必须充分考虑管土相互作用的特性。在考虑管土变形协调的基础上,将上埋式管道管周土压力问题归结为求解重力场下二维弹性介质内嵌弹性圆环的孔洞应力集中问题,得到了管周应力与位移的分布函数,并对管道土压力的计算图式进行了简化,最后通过算例将本文结果与其他方法结果进行了比较。

The infection of related factors to load transfer rule on cement-soil pile through the load transfer function method was analyzed according to the displacement harmony theory.The hyperbola model was taken as the load transfer function and the axial pile force was taken as iteration variable for compute iteratively.For verifying the validity the paper analyzes one engineering instance,the calculated curves of load-settlement of cement-soil pile is consistent basically with the measured curves.The error margin between the values of calcuation and the measure is even small,especially in the lower load condition.The results indicate that the higher load can make the side friction of the below pile bring into play sufficiently;enlarging modulus of compressibility can make the pile easier to carry the load to the deeper soil layer;the side friction reduces with the len-diameter growing;but the influence to the load transfer on cement-soil pile for angle of internal friction is not very effective.

根据位移协调理论,采用荷载传递函数法分析了竖向受荷下相关因素对水泥土桩荷载传递规律的影响。桩侧传递函数采用双曲线模型,以桩身轴力为迭代变量,进行迭代计算。为验证本文分析模型的有效性,对工程实例进行了数值计算,计算得到的水泥土桩荷载-沉降曲线与工程实测曲线基本吻合,尤其对于荷载水平较低的情况计算值与实测值误差更小。研究表明:较高的荷载水平能使桩体下部侧摩阻力充分发挥;增大弹性模量能使桩更容易将荷载传递到较深的土层中;侧摩阻力随长径比的增大而减小;而内摩擦角对水泥土桩荷载传递的影响不大。该研究结果对桩的设计和承载力的计算具有重要意义。
