| 摘 要： | 作者在本文中首先介绍了改进的Anas Abo-Zena传递矩阵法面波频散函 数的计算问题。这是一种高频时稳定的算法，适用于一般地基勘查和无损检测的面波频散函数计算。其次，还讨论了用Monte Carlo法求解面波频散函数的问题。并用这种算法和Newton迭代法进行了对比，显示了对于Newton迭代法不能计算的速度逆转剖面（即层速度自上而下逐层减递），Monte Carlo法也适用。

| Abstract: | This paper first introduces the modified Anas Abo Zena's method for computation of surface waves dispersion functions, which is a stable algorithm at very high frequency and can be used to compute the dispersion curves for site investigation and non-intrusive diagnosis. Then this paper discusses the solutions of the dispersion functions by Monte Carlo method and compares them with those by the Newton iteration method. The results show that Monte Carlo method can tackle the inverse velocity profile that is difficult to be resolved by the Newton iteration method. |
