现代建筑由于建筑用地越来越宝贵,所以不断向空间扩展,建筑物的高度不断增加,这就对建筑物的基础提出了更高的要求。钻孔灌注桩是以岩层作为持力层,由于桩身较长、摩擦力增大,所以承载力比浅基要大得多,符合高层建筑的要求,所以在中小城市应用得越来越广泛,本文结合某工程实例对钻孔灌注桩的施工技术进行分析。 As modern buildings are more and more valuable for construction land, they are constantly expanding in space and increasing in height. This poses higher requirements for the foundations of buildings. Bored piles are based on the rock as a holding layer, due to the longer pile, the friction increases, so the bearing capacity is much larger than the shallow base, in line with the requirements of high-rise buildings, so more and more widely used in small cities In this paper, an engineering example of bored pile construction technology analysis.
