大口径钻孔灌注桩荷载传递性状
The Load Tranfer Behavior of Large Diameter Cast-in-Situ Pile in Crushed Pebble Stratum
-
摘要: 本文通过五根桩身内埋设量测元件的试桩资料,分析桩的荷载传递机理与承载性状,以及施工工艺对其影响和作用。根据其荷载传递特点认为福州地区可利用含粘性土碎卵石层为大口径灌注桩持力层,打破传统打入式预制桩的格局。为今后合理选用桩型以及指导施工大有裨益。Abstract: The paper analyzed the load transfer behavior and bearing capacity characterstics of pile based on the in-site test data of five instrumented piles. It has been shown that the crushed pebble stra-tum can be used as the bearing stratum of the large diameter cast-in -situ pile in the region of Fuzhou.
