摘要
通过对静压PHC管桩的静载Q-s曲线呈台阶状之原因分析,提出了相应的施工变量控制措施,以避免桩体上浮、桩节焊缝开裂处脱节,桩体和桩端密实持力层脱密。
PHC is a new pile type developed in the past two years. The load-settlement curve is more often step-shaped than other pile types. Based on the analysing of three typical cases, construction control methods are offered to decrease the problems during static piling.
