摘　　要：本文基于Midas Civil,运用m法模拟了桩土相互作用对高速铁路连续梁桥地震响应的影响。实验发现,考虑桩土相互作用时,地震响应明显增大,且地震响应规律差异明显。这是准确计算地震对高速铁路连续梁桥影响的不可忽略因素。This article bases on Midas Civil, use the method of m to simulate the pile-soil interaction impact on the seismic response of continuous beam bridge in high-speed railway. And the author discovers that when considering the pile-soil interaction, the seismic response is significantly increased, and the differences of the seismic response law are obvious, which is the factor that cannot be ignored to accurately calculate the earthquake on the continuous beam bridge in high-speed railway.
