日本东京城区四个场地的土层放大效应分析(英文)

AMPLIFICATION OF THE SURFACE LAYERS AT FOUR SITES IN TOKYO, JAPAN, URBAN AREA

本文用统计一经验格林函数法合成１９２３年关东地震近场加速度时程，对比分析东京城区四个相近场地的土层放大效应，说明在结构抗震分析中考虑土层放大效应的重要性。

The accelerations in an epicentral region of the 1923 Kanto earthquake were synthesized by a statisicalempirical Green's function method. The synthesized results on base rock and soil surface at four sites in Tokyourban area were compated. The comparison implies that the amplification of the surface layers must be wellconsidered.
