摘　　要：根据4根桩身内埋设量测元件的试桩资料,分析了江苏地区超深钻孔灌注桩的荷载传递机理 和承载性状。认为苏州地区的钻孔灌注桩具有纯摩擦性的特性,即桩端分担的荷载很小。It is analyzed that the load transfer behavior and bearing capacity characteristics of pile based on the in-situ test data of four instrumented piles. It has been shown that cast-in-situ pile has character of friction pile, that is to say,end point of pile shares very small load in the region of Suzhou.
