［摘要］西藏中學男生宿舍樓為6層磚混結(jié)構(gòu)，建于1985年，經(jīng)鑒定需要對其進行抗震加固。為盡量減少施工過程中對建筑使用的影響，降低綜合造價，采用了隔震加固方法。探討了采用隔震技術(shù)對多層砌體房屋進行隔震加固的計算分析方法、施工工藝及相應的關(guān)鍵技術(shù)。分析結(jié)果表明采用隔震技術(shù)進行抗震加固，可通過降低隔震層上部結(jié)構(gòu)的抗震設防烈度來降低其抗震構(gòu)造要求，從而使其滿足抗震鑒定標準，達到抗震加固的目的。此外，采用隔震加固方法，對原建筑使用功能、內(nèi)部裝修、管線等影響較?。ǔ讓油猓?，可減少內(nèi)裝修和管線恢復的費用。

Abstract: Tibetan Middle School boys’dormitory built in 1985 is a six-story brick and concrete composite structure. Isolation reinforcement methods were used in order to minimize the impact of the building construction process and reduce the comprehensive cost. Computational analysis method, construction technology and the key technologies using isolation technology are discussed for multistory masonry buildings reinforcement. The analysis results show that using isolation technology for seismic reinforcement can reduce the seismic construction requirements by reducing the seismic intensity of the superstructure of the isolation layer, and make it meet the seismic qualification standards to achieve the purpose of the seismic reinforcement. The reinforcement method using isolation technology will impact small on functionality, interior decoration, and pipelines of the original building (except for the first floor), and can reduce the cost of interior decoration and pipeline recovery.

Keywords: brick and concrete composite structure; seismic reinforcement; isolation technology
