针对深基坑H型钢桩静载承载力检测需求,结合项目特点合理利用临近的H型钢桩采用锚桩法进行单桩抗压静载试验,很好地解决了受场地条件限制,传统堆载无法完成的难题,具有较好的经济性与实用性。本次锚桩法所测得的H型钢桩的位移沉降量相对较大,建议H型钢桩极限承载力根据承台内钢桩与混凝土灌注桩协调变形工作机理综合取值。
According to the requirement of testing the static load bearing capacity of H-section steel piles in deep foundation pit and using the characteristics of the project, it is reasonable to use the adjacent H-shaped steel piles to carry out single-pile static pressure test with anchor piles method. Unable to complete the problem, with good economy and practicality. The displacement settlement of H-shaped steel piles measured by this method is relatively large. It is suggested that the ultimate bearing capacity of H-shaped steel piles should be determined according to the coordination mechanism of steel piles and concrete bored piles.
