摘　　要：通过埋有钢筋应力计和沉降杆的大直径锤击沉管灌注桩的静载试验,研究其荷载传递机理和承载特性,分析端阻力和侧阻力的变化规律。提出沉降杆的观测有利于桩身压缩量和桩端阻力的研究分析。Base on the static loading tests on Large Diameter Driven Cast-in-situ (LDDC)piles with stain gagues and telltale installed in the piles, the load transfer mechanism and bearing behaviors of LDDC piles was studied, the behaviors of toe resistance and skin resistance was analyzed. The view of the telltale readings is useful for the analysis of pile compression and toe resistance was presented.
