摘要

汶川地震以后,国务院成立全国中小学校舍安全工程领导小组,统一领导和部署中小学校舍安全工程。在全国范围实施校舍安全工程,全面改善中小学校舍安全状况,在全国中小学校开展抗震加固、提高综合防灾能力建设,使学校校舍达到重点设防类抗震设防标准。根据中小学校舍抗震鉴定加固工程委员会的要求,需对原结构按照新规范进行全面检测和抗震鉴定,本文结合某工程实例,采用一种较好的抗震加固方法—钢筋混凝土板墙加固法。它具有较大刚度、强度,有良好的变形和延性,对提高抗震能力有显著作用,施工快,综合效益好。对加固方法做了一个全面的论述,以供今后的类似工程参考。
After Wenchuan earthquake,a safety engineering leadership team has been established countrywide for middle and primary school buildings by the state council to deploy the primary school buildings in safety engineering. Carrying out the seismic strengthening and improving synthetic disaster prevention ability construction is to make schoolhouse reach key fortification of anti-seismic standards.According to the seismic appraisal and hardening of primary and secondary school building's request,they need to be reinforced.In this paper,combining with a project example, a better seismic strengthening methods—reinforced concrete masonry wall reinforcement was used.It has a bigger stiffness and strength,and its deformation and ductility is favorable,So that the earthquake-resistant ability was improved significantly and comprehensive benefit is good.Overall discusses of the strengthening method were carried out in this paper,which could be serverd as a reference for similar practical application.
