【摘要】 汶川地震因房屋倒塌和危房拆除产生了大量的建筑废物,对建筑废物的处理关系到灾后重建能否顺利有效地进行。首先在汶川地震震害情况统计的基础上,依据不同结构形式房屋与建筑废物的关系,指出了砌体结构、框架结构和砌体—框架混合结构为建筑废物的主要来源,并初步建立了灾区建筑废物总量的数学模型,然后从结构、材料和破坏情况的角度对建筑废物的种类和数量进行了统计分析,总结了灾区建筑废物的组成和分布特点:建筑废物主要为废混凝土和废砖,其主要来源为砌体结构。更多还原

【Abstract】 A huge amount of building waste was caused by collapsed houses and dilapidated buildings as a result of Wenchuan earthquake.The smooth disposal of building waste will make the post-earthquake reconstruction work effective.Based on the statistics of the earthquake damage and the relationship between different building structures and building waste produced,it was indicated that masonry structures,frame structures and mixed structures between them are the main source of building waste.An initial mathematical model about the amount of building waste in the disaster area was firstly set up,then the type and the quantity of building waste were statistically analyzed from the aspects of structure,materials and damage situation.Finally,the composition and distribution characteristics of building waste in disaster area were concluded as:the main building waste is waste concrete and waste brick,and most of it comes from the masonry structures.更多还原
