摘　　要：本文用IADI法(交替方向隐式差分法和迭代法的综合)求解柱坐标系下的三维轴对称固结方程,并结合其具体的初边值条件,将该方法应用到破井排水加固地基的固结计算中去。通过实例计算验证了该方法的实用性和可靠性。Using IADI method (a synthesis of the successive ?directed implicit differential method and the iteration method), this paper finds the solution of three dimensional axisymmetrical consolidation equations under the cylindrical coordinate system ?Combining with concrete initial and boundary value conditions , this method is applied in the consolidation computation of the sand ?well drainage to strengthen the foundation. By the computation of case histories . the practicality and reliability of this method are verified .
