任意轴对称荷载作用下的圆杆分析

ANALYSIS OF CIRCULAR CYLINDER UNDER ARBITRARY AXISYMMETRIC LOAD

  • 摘要: 锚杆与周围介质相互作用问题涉及圆杆在轴对称荷载作用下的应力应变分析,本文提出一种付里叶方法来分析圆杆在任意轴对称荷载作用下的位移场和应力场,而且考虑了付里叶级数中任意两项的耦合。为了验证这一方法的正确性,本文还导出圆杆在均匀轴对称荷载作用下的理论解。分析成果表明所提方法对于任意轴对称荷载作用下的圆杆问题具有相当好的精度,分析时必须考虑付里叶级数中任意两项的耦合作用。

     

    Abstract: The interaction of grouted anchor and its surrounding medium is a very complex problem. To obtain the stresses and the displacements on the interface between the anchor and its surrounding medium, the analysis of a circular cylinder under arbitrary axisymmetric loads should be done. In this paper a method for analyzing stress and displacement field of a cylinder loaded with arbitrary axisymmetric normal force and shear force is proposed, in which Fourier method is adopted and the coupling between arbitrary two terms of the Fourier series is considered. To verify the effectiveness of this method a theoretical solution for circular cylinder under uniform axially-symmetrical load is derived. The good agreement between the two methods confirms that the proposed approach is capable of predicting the stresses and the displacements for a cylinder under arbitrary axisymmetric loads, and the results possess higher accuracy if the coupling effect is considered.
