Experimental Analysis of Bearing Characteristics of Large-diameter Deep Rock-socketed Pile in Qingdao Gulf Bridge
摘要
Abstract
Four large-diameter rock-socketed piles in Qingdao Gulf Bridge were tested for their static load using self-balanced testing technology. Then the bearing characteristics - load displacement curve of large- diameter rock-socketed pile （with rock ratio more than 3 ）, the relationship between lateral resistance and displacement, and the sharing ratio between lateral resistance and end resistance are analyzed. Through comparing three standards, the value and existing problems of different standard are analyzed. The results obtained from self-balanced testing method and anchor pile method are compared to provide evidence for determination of the bearing capacity of large-diameter rock-socketed pile foundation in this area.关键词
