县级城市的设计地震动分区方法

The Method of Earthquake Microzonation for County Town

作者针对一般县城有关设计地震动分区基础资料不完备的情况 ,提出适合县城的设计地震动分区方法。在这个方法中 ,工作区工程地质的正确评价是地震动分区的基础 ;如何正确地确定抗震设防基岩运动和各区的设计地震动参数是获得合理结果的关键 。

In view of the insufficient basic data in ordinary county towns, a method of earthquake microzonation suitable for county towns is presented. The accurate evaluation of engineering geology in the working area is the basis of earthquake microzonation. The correct determination of the bed rock motion and design ground motion parameters at each zone are the keys to obtain rational results.The microzonation of a county is given as an example to explain the procedure.
