深基础施工是高层和超高层建筑施工中的一个突出问题。由于对地基土认识不足以及设计方法存在问题等,使得深基坑开挖风险相当大。深基坑开挖施工与前后施工环节搭接密切,前期围护结构没有质量保证或后期底板没有及时施工,都可能引起工程事故。 Deep foundation construction is a prominent issue in the construction of high-rise and super-tall buildings. Due to the lack of understanding of the foundation soil and the design method of existing problems, making the risk of deep excavation quite large. Excavation of deep foundation pit construction is closely linked with the construction process before and after, the pre-construction envelope has no quality assurance or the late bottom plate is not constructed in a timely manner, all of which may cause engineering accidents.
