摘要
2008 年发生的汶川大地震以及 2010 年的玉树地震,造成了大量房屋倒塌,由此
造成了严重的生命安全与财产损失。由于我国绝大部分地区村镇建筑缺乏系统规划
设计,建造质量低劣,房屋抗震能力差。砌体结构房屋材料脆性大,自重大,在无
可靠的构造措施(如圈梁,构造柱拉结等等)情况下,难以抵抗破坏性地震作用。
基于此,本文借助国家“十一五”科技支撑计划子课题《村镇既有砌体结构住宅加
固改造关键技术研究》的平台,通过实地考察,全面展示了我国村镇既有砌体结构
房屋的现状。 
本文首先从基础形式,墙体做法,结构形式,构造措施,屋面结构,门窗洞口
等方面全景式地调查分析了村镇砌体结构房屋的现状及其存在的问题,并提出了相
关的改进措施。 
针对村镇砌体结构的承载能力,本文从砌体材料的材性试验着手,选取实地取
样的砖块,按照调研成果调配的砌筑砂浆试样,进行砖块抗压试验,以比照村镇砌
体结构房屋材料的真实强度等级与理论值的区别,进而较为全面地掌握当前村镇砌
体结构房屋的建筑材料性状。 
然后本文针对村镇砌体结构房屋的结构形式,房屋类型尺寸以及存在的共性问
题,结合我国村镇的实际经济条件,提出了具有代表性的典型结构形式,再针对这
种结构形式,探讨采用镀锌铁丝替代钢筋加抹水泥砂浆的加固方法。

Abstract
In recent years, the masses earthquakes have caused severe life safety and property
losses and a large number of houses collapse to our country, especially in 2008 wenchuan
earthquake happened and 2010 in yushu. Because our village houses in many areas which
are lack of planning design, in the inferior quality and poor anti-seismic grade. Its
brittleness characteristics, too large gravity and lower seismic performance under the
action of destructive earthquakes in above are adverse problems, except of perimeterbeam
and tectonic column performance. On the basis of masonry structure in Chinese rural areas
widely distributed characteristics, this research draw the outline of our current brick
masonry structures in rural areas in terms of on-the-spot investigation and survey on the
platform of National 11th five-year plan science and technology support—sub task
“Current bourg masonry structure housing reconstruction reforcement key technical
research”,and make some analysis latter.
Firstly, this thesis emphasizes to study the current situation of brick masonry
structures in rural areas, including groundwork, masonry walls, structure style,
consturctional detail, roofing accessory
