摘　　要：运用ANSYS软件、以简化荷载结构模型为计算模型,对重载铁路隧道结构进行了单线和双线隧道结构计算,并与实测值进行了对比。结果表明,无论是单线隧道还是双线隧道,采用简化荷载结构模型对重载铁路隧道线路的动力特征进行模拟,计算结果值与实测结果可以实现包络,且计算值与实测值在不同区域的分布规律基本一致;采用简化荷载结构模型对重载铁路隧道线路的动力特征进行模拟,计算结果与实测结果基本吻合,可以有效对重载铁路隧道线路进行结构计算与优化。Using ANSYS software and simplified load structure model as calculation model,the single line and double line tunnel structure of heavy load railway tunnel is calculated and compared with the measured value.The results show that the simplified load structure model can be used to simulate the dynamic characteristics of the heavy haul railway tunnel line.The simplified load structure model is used to simulate the dynamic characteristics of the heavy-duty railway tunnel line.The calculated results are basically consistent with the measured results,which can effectively calculate and optimize the structure of the heavy-duty railway tunnel line.
