摘要: 通过对某局部倾斜建筑物不均匀沉降和上部结构受损情况调查,分析该建筑物产生不均匀沉降后其受力及变形特点,给出建筑物局部倾斜基本特征及其与整体倾斜的区别. 并根据局部倾斜特征将建筑物分为“刚性转动区”和“转动协调区”,进一步对不同类型的“转动协调区”的受损特征及其影响因素展开分析. 分析结果表明,纠倾处理时以“分区处理,整体协调”为总体思路,对“刚性转动区”进行局部顶升复位,对不同类型的“转动协调区”视情况采取截柱迫降、设置纠倾分隔带、受损构件加固、采用拉区围箍式联合顶升承台实施顶升等措施,可取得良好的纠倾效果.

Abstract: Through the investigation of the uneven settlement and superstructure damage of a partially inclined building, theforce and deformation characteristics of the building after the uneven settlement were analyzed, and the basic characteristicsof partially inclined buildings and its difference form the overall inclined buildings were given. According to thecharacteristics of partially inclined, the building was divided into " rigid rotation zone" and " coordinated rotation zone" ,and the damaged characteristics and influencing factors of different types of " coordinated rotation zone" were furtheranalyzed. The analysis results show that the rectifying tilt processing with " partition processing and overall coordination" asthe general idea, local jacking resetting the " rigid rotation zone" ,taking the measures of rectifying column landing, settingdisconnected area damaged component reinforcement and uniting hoop stirrup in tensile zone and cushion caps for differenttypes of " coordinated rotation zone" have achieved good rectifying effect.

Keywords:partially inclined; rigid rotation zone; coordinated rotation zone; integrated incline-rectifying by region;rectifying column landing; uniting hoop stirrup in tensile zone and cushion cap
