摘　　要：地处湿陷性黄土场地不均匀沉降的既有住宅楼,其隐患治理首先要对地基基础进行加固,制止不均匀沉降,再进行纠偏处理,并辅助以上部结构加固补强与维修,使建筑恢复正常使用功能。既有建筑加固施工质量的检测与评估贯穿于施工的全过程,加固施工阶段对各类型原材料进行试验检测,保证所用材料的质量与安全;分部分项工程施工过程阶段,对阶段性成品抽查进行试验与检测,评估加固工程成品的施工质量与安全性;施工完成后,再对已完工住宅楼整体进行安全性鉴定和抗震鉴定。通过这三个层次方能完全评定加固工程施工质量,评估加固后建筑的安全性能与抗震性能。The existing residential buildings located in the uneven settlement of collapsible loess site,its hidden trouble control should first reinforce the foundation,prevent uneven settlement,and then rectify the deviation,and assist the above part of the structure reinforcement and repair,so that the building to restore the normal function.The inspection and evaluation of construction quality of existing building reinforcement runs through the whole process of construction.During the reinforcement construction stage,various types of raw materials are tested and tested to ensure the quality and safety of the materials used.During the construction process of sub-project,test and test the periodic finished products by spot check,evaluate the construction quality and safety of the finished products of the reinforcement project.After the construction is completed,the whole of the completed residential building is appraised for safety and seismic appraisal.Only through these three levels can the construction quality of the reinforcement project be assessed completely,and the safety performance and seismic performance of the reinforced building be assessed.
