摘要

本文提出了波在隧道中传播的抛物方程方法。为了求解抛物型方程，引入了分步傅里叶变换。然后给出了描述复杂气象环境的折射率表达式。通过修正PE的折射率，可以预测隧道中的波传播。

Parabolic Equation Method Solving Wave Propagation in Tunnels in Complex Meteorological Environments

In this paper, a parabolic equation method for wave propagation in tunnels is raised. To solve parabolic equation, split-step Fourier Transform has been introduced. Then the expressions of refractivity describing the complex meteorological environment are provided. The wave propagation in tunnels can be predicted by amending the refractivity in PE.
