摘要
在综述国内外对桩基础竖向承载能力研究现状的基础上,制定了天津滨海国际机场第二跑道工程场外试桩方案,对施工现场3根钻孔灌注桩进行了静荷载试验,并对现场预埋元件进行实际观测和测读,系统的分析了桩基础在受竖向荷载作用时的受力机理,为未来同类地质条件下的桩基础设计提供科学的依据。
This article, schemes the test pile establishing of Tianjin Binhai International Airport second runway project, does static loading tests on three piles in construction site, and does practical observation and measuring reading pre-buried elements in site, based on review of pile foundation compressive bearing capacity at home and abroad. The article systematically analyzes of the stress mechanism of pile foundation under compressive loads, it provides scientific basis for the pile foundation design under similar geological conditions in the future.
