摘要
在现场试桩和室内模型试验基础上,探讨了嵌岩桩的承载特性和破坏模式。分析认为,在不同地质条件和设计方法下,嵌岩桩可表现为摩擦型桩或端承型桩的承载性状;嵌岩桩的破坏模式与桩岩相对刚度有关,破坏可发生的位置有:(1)桩岩界面;(2)桩周围岩中;(3)桩体本身。
Based on the field loading test and the laboratory model test, the bearing behaviors and the failure mode of rock-socked pile foundation are discussed. The results of the analysis show that the rock-socked pile posses the loading behaviors of friction pile or end bearing pile, which is dependent on geological condition and design methods. The failure mode of rock-socked pile is related to the relative rigidity of pile and rock, and the failure may occur in (1) the interface of rock and pile, (2) the rock around the pile and (3) the pile itself.
