传统抗震加固技术和新型抗震加固技术的总结与对比

Summary and Comparison of Traditional and Innovative Seismic Strengthening Technologies

收集和整理了目前在工程中常见的一些抗震加固技术,按传统抗震加固技术和新型抗震加固技术分别进行介绍。传统的抗震加固技术主要针对混凝土结构和砖混结构,以增大截面法、外包钢加固法、置换混凝土加固法、粘钢加固法和粘碳纤维加固法等为例进行介绍。新型加固技术一般可分为抗震加固、减震加固和隔震加固三大类,每种类型都有不同的加固方法。这些加固方法大都运用了目前较为先进的科学技术,加固效果较为明显,但是造价也相对较高。

In this paper,the seismic strengthening technology was divided into the traditional and the innovative seismic reinforcement technologies.Traditional seismic strengthening technology is mainly used in the concrete structures and brick structures.This paper introduced the main technologies such as increasing the cross-section,sticking steel plates,replaceing concrete,bonding steel reinforcement,sticking carbon fiber reinforcement and so on.The innovative reinforcement technologies such as seismic reinforcement,damping reinforcement,isolation reinforcement were also introduced.Most of these strengthening methods use advanced science and technology and have obvious efficiency,but the cost is relatively high.
