Estimation and recycling of post-earthquake construction waste and grouting strengthening method of masonry

Abstract

我国是一个地震灾害频繁的国家,对地震后产生的建筑垃圾的估算和建筑垃圾再利用途径的探索,对于抗震减灾和震后重建具有重要的指导意义。本文在对比了传统的建筑垃圾估算方法的基础上,创新性地利用遥感技术进行震后建筑垃圾产量的估算。以5.12汶川大地震为例,估算结果为3.14亿吨,和国内应用其他估算方法所得结果相近,估算也表明遥感技术在建筑垃圾估算法准确、高效,值得推广。在建筑垃圾再利用途径的探讨中,在总结国内外现行的建筑垃圾处理方法和技术的基础上,探讨我国建筑垃圾处理的途径,并进行了效益分析。分析表明建筑垃圾的技术途径多样、可行。 我国目前地震建筑垃圾主要来源于砌体,砌体的加固至关重要。本文创新性地提...China is an earthquake-prone country. It has important guiding significance mitigating earthquake disasters and rebuilding if estimation of construction waste and recycling ways are available. In contrast to the traditional methods of estimating construction waste, a new method using sensing technology is proposed. In this way, the quanlity of construction waste lead by 5.12 Wenchuan earthquake is...学位:工学硕士院系专业:建筑与土木工程学院土木工程系_结构工程学号:2532007115219
