| 摘 要： | 在传递矩阵法的数值计算中，积分变量ξ可引起较大的误差。以轴对称问题的传递矩阵法为基础，将不含1／ξ的项和含1／ξ的项区分开来，在数值计算时分别采用两套传递矩阵：初始传递矩阵和修正传递矩阵，可将ξ引起的误差降至极小。

| Abstract: | On the basis of the transferring matrix method, which is an explicit solution for axisymmetric problem in layered elastic half space, the calculation method given in this paper can reduce the error, which is caused mainly by the integral variable . The terms can be divided into two kinds. One includes 1 and the other does not. For different cases, different transferring matrixes, should be chosen the modificatory transferring matrix and the preliminary transferring matrix according to whether the term contains 1 or not. |
