[摘要] 廣州某工廠宿舍樓建于20世紀(jì)90年代初，由于日常使用、管理不當(dāng)，在酸性腐蝕環(huán)境作用下，部分構(gòu)件的鋼筋出現(xiàn)不同程度銹蝕，導(dǎo)致結(jié)構(gòu)性能衰退。對(duì)其進(jìn)行檢測(cè)鑒定，綜合考慮技術(shù)可靠、經(jīng)濟(jì)合理和方便施工等因素，比較多種加固方法選擇較優(yōu)方案。經(jīng)加固處理，該結(jié)構(gòu)耐久性滿足現(xiàn)行規(guī)范要求和承載安全的要求。以該建筑為鑒，指出一般建筑要注意日常使用和維護(hù)；在加固設(shè)計(jì)中，應(yīng)當(dāng)根據(jù)結(jié)構(gòu)特點(diǎn)和加固方法的適用性進(jìn)行多方案的分析、比較，選擇較優(yōu)的方法，切實(shí)做到技術(shù)可靠、經(jīng)濟(jì)合理、方便施工。

Abstract: The domutory of a typical factory in Guangzhou was constructed in 1990s. Due to the improper utilization and management, in addition to the damage of acidic corrosion environment, steel corrosion has been found in different parts of constructional elements, which has led to architectural functional recession. After studying and detecting, we synthetically take the tecluucal, financial, constructional elements into account, trying to find out the reliable scheme beneficial to the reinforcement. After the reinforcement, the structure meets the requirements of durability and load safety. The dormitory of a typical factory in Guangzhou as a warrung to the study, general building and maintenance of daily use in mind; in the reinforcement, the reinforcement should be based on structural characteristics and applicability of the method for multi-program analysis, comparison, and optimum way selection to make sure technology is reliable, economical, convenient construction.
Keywords: detection; reinforcement, steel corrosion
