摘要
通过对甘肃省土坯房的不同地区现场调查,获取了大量的基础数据资料,经过分类整理和分析研究,取得了以下主要结果:(1)按照承重方式的不同,土坯房可分为墙体承重、砖柱(木柱)承重和混合承重3个类型,并给出了其在甘肃省的空间分布特征;(2)讨论了对土坯房震害影响最大的地震动特性、场地条件、结构类型等几个因素;(3)结合2003年甘肃省民乐-山丹6.1级地震、岷县-临潭-卓尼5.2级地震以及2008年汶川8.0级地震中土坯房的震害表现,在土坯房分类基本原则的基础上,提出了甘肃省土坯房多因素分类方法,并给出了针对现有土坯房的评定准则,通过准则能够获知目前甘肃省土坯房现状及其防御地震能力的综合评价信息。
A great amount of basic data about adobe houses in Gansu Province obtained by field investigation are analyzed. In our study, the adobe houses are divided into three types in terms of load-bearing mode, i.e. wall beating, brick column/wooden pillar bearing, and mixed combination bearing. In this paper regional distribution characteristic of the adobe houses is given, and the important factors such as characteristics of ground motion, site conditions and structure type are discussed. On the base of adobe house type codes, combined with the damage characters in 2003 Minle-Shandan earthquake （Ms6.1）, Minxian-Lintan-Zhuoni earthquake （Ms5.2） and 2008 Wenchuan earthquake （Ms8.0）, multi-factor classification and assessment criteria about adobe houses in Gansu is given. Our results are valuable in understanding of the current conditions and the anti-earthquake ability of adobe houses in Gansu Province.
