中小城镇地震动影响小区划的一种建议方法

A recommended method of the ground shock effect on the microzonation in medium and small towns.

本文在现行烈度区划图和新编抗震设计规范有关规定的基础上,为减小和避免在应用中对各种参数理解的差异以及参数本身所具有的不确定性,结合中小城镇编制防灾规划的特点和要求,提出考虑烈度、场地分类和远、近震模糊性的地震动影响小区划方法,可供中小城镇编制抗震防灾规划时参考。

This paper presents a method of microzonation considering the earthquake intensity, site classification and fuzziness effect of far and near ground shocks. The basis is the present earthquake intensity region map and related regulations of the newly edited anti-seismic design code. It aims to minimize and avoid the difference in understanding the parameters in the applications and the uncertainties of the parameters themselves. This meets the peculiarities and requirements of antihazard planning for medium and small towns, all these materials are useful in these planning.
