【摘要】 现行研究地震行波效应的理论公式是假设考虑行波效应后不同点间的相位差与两点在行波前进方向的投影距离成正比,与行波波速成反比,其合理性需要实际地震监测资料的证实。本文结合Mauvoisin拱坝的实际地震资料,分析大坝动力分析时考虑行波效应的必要性。更多还原

【Abstract】 The theoretical formula currently used for studying travel wave effects of earthquake is based on the following assumption. After the travel wave effect is taken into consideration, the phase difference between different points is proportional to the projection distance of the two points along the travel wave forwarding direction, and is inversely proportional to the travel wave velocity. Its rationality requires to be verified by monitored seismic data. In this paper studying the measured seismic data of Mauvoisin arch dam, is to discuss the necessity of considering traveling wave effects when the dam dynamic analysis is taken into consideration.更多还原
