摘要

随着大规模调水工程的建设

穿越软土地区的浅埋输水隧道的抗震性能的重要性愈加突出

这就涉及到地震动的输入问题。而对于空间尺度很大的大型输水隧道

地震动输入的空间变化特性即多点输入对输水隧道的地震响应产生重要的影响。所以在考虑了衬砌-水体-围岩的相互作用的同时

还考虑了地震波有限波速传播所引起的行波效应及不同地震动激励方向对三维输水隧道的地震动的影响。结果表明:与地震动一致输入相比

行波效应将对输水隧道的地震响应产生不利的影响。

Abstract

The aseismic performance of shallow buried water-supplying tunnel in soft soil area is becoming more and more important with the development of large-scale water transportation. The problem of earthquake input pattern has been referred. For large-scale water-conveying tunnel

the spatial variation characteristics of earthquake excitation

namely

multi-point input has great effects on seismic response of the water-conveying tunnel. Aim at this problem

the paper considers interaction among surrounding rock tunnel lining and water

at the same time

traveling wave effect and influence of different exciting direction of earthquake motion. The result indicates: compared with the coincident earthquake excitation

traveling wave effect brings disadvantageous influence on seismic response of the water-conveying tunnel.
