建筑物纠倾技术及其工程应用
|
摘要
勘察、设计、施工、使用或环境的不良影响是既有建筑物可能会出现倾斜的重要因素。纠倾方案的合理选取与实施是避免建筑物因拆除而产生损失,保证建筑物生产或生活不受影响、名胜古迹不受破坏的基础和前提。文章阐述了国内外建筑物纠倾技术的研究现状,比较分析了几个较典型纠倾工程的案例,从上部结构、地基以及外部环境的影响等方面分析了建筑物的倾斜原因,总结了顶升法和迫降法等几种常用的纠倾方法,明确了在纠倾过程中应考虑土体侧压力和动态扰动的影响,鼓励采用新方法、新技术模拟掏土开挖;阐明了土体塌陷时采用非连续变形分析方法与连续变形分析方法局部耦合,综合运用多种分析手段,建立健全的纠倾技术体系,展望了建筑物纠倾技术的研究趋势。
Due to the adverse influences of survey,design,construction,usage or environment,the building may be inclined.Rational selection and implementation of incline-rectifying solution,can avoid the demolition waste,ensure that production and life are not affected and that places of historic interest is not destroyed.In this paper,advances of building incline-rectifying technology at home and abroad are analyzed,several typical incline-rectifying projects are introduced simply,and incline reasons and common rectifying methods are summarized from the aspects of the upper building,foundation and surrounding environment.Rectifying methods can be divided into force to settle method and lift-up method,and in the meantime,suggestions on building's incline-rectifying technology are put forward.The influence of soil's lateral pressure and soil-digging's dynamic disturbance should be considered,new methods or new technologies are encouraged to use to simulate soil-digging process.Analysis of soil's collapse can use the coupled method of discontinuous deformation method and continuous deformation method,etc.Engineering application can move successfully,only when varieties of analysis methods are integrated and perfected system of incline-rectifying technology is established.
