混凝土加固技术在建筑结构的应用作者(山东大学土建与水利学院余建辉土木工程 2班 201200202152) 摘要: 通过建筑作为一个长期的消耗品,其使用时间是有周期限制的。并且受到其使用环境的影响,例如外界环境、地质灾害等,都会对建筑结构使用周期造成影响,致使其安全寿命缩短,因此针对建筑需要施行安全鉴定,并针对建筑结构进行适宜的加固和改造。合理、科学的结构加固、改造能够有效延长建筑结构使用周期,提高建筑的安全性能, 从而避免了建筑还没到使用周期便被拆除的不利影响。混凝土结构加固业已成为我国建筑业中一个新的发展热点,与之相应的混凝土结构加固技术也成为结构工程中重点研究的领域之一。通过概述混凝土结构加固技术现状,介绍混凝土结构加固的众多方法, 分析了各种方法的特点和适用范围; 并对混凝土结构加固技术目前需要完善的地方以及发展方向提出几点建议。关键词: 混凝土结构; 加固; 现状; 方法 The application of technology in the building structure reinforced concrete ( School of Civil and Hydraulic Engineering, Shandong University Yu jianhui 201200202152 ) Abstract : Through the building asa long-term consumables, its use time isa week through the building asa long-term consumables, its use have limited period of time. And influenced by its usage environment, such as the external environment, geological disasters, etc., will affect structure using cycle, leading to the safe life expectancy, so in accordance with the need of building safety appraisal, and suitable for building structure reinforcement and reconstruction. The rational and scientific structure reinforcement and reconstruction can effectively prolong the lifetime of building structure, improve the safety performance of construction, so as to avoid the demolition ofa building are not used to the cycle. Reinforced concrete structure has e a new hotspot of development in construction industry in our country, the corre
