摘　　要：对安徽某特大桥基础3根大直径嵌岩桩的现场施工进行了监测,分析了其在施工过程中的承载特性和受力机理等情况。监测结果表明:嵌岩桩的侧摩阻力在加载过程中出现了2个峰值,随着荷载的继续增加,上峰值有增大的趋势。The paper monitored the construction of three large diameter socketd piles of a grand bridge in Anhui province, which includes the load on the pile head, the pile body stress and the pile head settlement and also analyzed the load bearing characteristics and stress mechanism during the construction process. The monitor result indicated that there appeared two peak in the loading process, and the lower peak value had the tendency to increase along with the load increasing.
