一些特殊地形对SH波传播的影响
SOME SPECIAL TOPOGRAPHY: THEIR INFLUENCES ON THE PROPAGATION OF SH-WAVES
-
摘要: 本文导出了 SH 波在平台、洼坑平台和陡坎地形中传播的理论解,找出震害调查中孤立突出的山梁震害加重的原因,并比较了陡坎地形和单表土层卓越周期公式的异同点.Abstract: The present paper deals with the theoretical solutions of propagation of SH waves in the platform, pitted-platform and steep-stepped types of topography. It works out an explanation of earthquake intensification in isolated mountain ranges as found in recent seismic hazard surveys. At the same time a comparison of the similarities and differences of the predominant period formula for steep-stepped topography and a single surface layer has been made.
