缺乏勘察资料城区的场地类别分区方法

Site Zoning Methodology for Urban District Lack of Investigation Data

为有效解决城市防灾规划中缺乏勘察资料城区的场地类别分区问题,采用贝叶斯理论,利用已划分的类似场地上的地震环境和场地环境信息,估计场地类别,并根据地震地质、工程地质和场地环境的资料对缺乏勘察资料的规划发展区域进行场地类别分区．文中以泉州市抗震防灾规划的场地分类工作为例,提出了采用该方法进行场地类别分区的基本步骤．该技术方法在泉州、厦门等地防灾规划中均应用效果较好．

In this paper, in order to solve the problem of site zoning for urban district, which lack of Investigation data in planning urban hazardous prevention, method of estimating site category based upon Bayes theorem is adopted by means of seismic and site information of those sites that have been classified and zoned in the involved city. Furthermore, site zoning can be gained by further integration with the seismic geological, engineering geological and ground surroundings＇ information. The example of Quanzhou city is presented subsequently, and basic procedure of site zoning by using this method is brought forward, too. This methodology has been applied in planning of Quanzhou and Xiamen with good effect.
