近年来,随着我国建筑行业的蓬勃发展,城市土地资源日益紧缺,为提高土地的利用率,高层建筑已经在现代城市建筑中占据了主体地位。高层建筑由于建筑高度大、层数多、混凝土方量大、结构自重也非常大,这就对地基的承栽力要求非常高,因此高层建筑的基础埋置深度都很深,基础一般都嵌入到微风化岩层中。另外,高层建筑的地下室不仅仅要满足停车要求,还要满足人防工程要求,施工过程中还要解决结构抗浮问题.这就要采用深基坑来建设多层地下室。深基坑施工牵涉到围护、防水、防坍塌等问题.其施工也是非常复杂且不确定因素多。高层建筑物工程复杂多样.子系统多,专业性强。质量要求高。这其施工管理更是提出了更高的要求。
In recent years, with the vigorous development of China’s construction industry, the urban land resources are increasingly scarce. In order to improve the utilization rate of land, high-rise buildings have occupied the dominant position in modern urban construction. High-rise building due to the height of the building, the number of layers, large amount of concrete, the weight of the structure is also very large, which on the bearing capacity of the foundation is very high, so the high embankment deep foundation, the foundation are generally embedded To slightly weathered rock formations. In addition, the basement of high-rise buildings not only to meet the parking requirements, but also to meet the requirements of civil air defense projects, but also to solve the problem of anti-floating structure during construction, which will use deep foundation pit to build multi-storey basement. The construction of deep foundation pit involves such issues as enclosure, waterproofing and collapse prevention, etc. Its construction is also very complicated with many uncertainties. High-rise buildings complex and diverse projects. Subsystems and more professional. High quality requirements. This construction management is put forward higher requirements.
