| 摘 要： | 针对山区地质地貌特征，提出了用于电力铁塔的新型卡盘式桩。用有限元方法对比分析在2种不利工况下陡峭山坡上卡盘式桩和传统直柱式桩的承载形态。分析认为：卡盘式桩能有效改善桩体的抗拉拔能力，但对于抗压能力提高作用甚微；科学地认识桩-岩石界面特性是客观评估嵌岩桩承载力的前提。

| Abstract: | In view of the geology and landform features in mountainous areas, a kind of Kapan pile was proposed for the foundations of dectric power towers. The deformation behavior and beating capacity mechanism of two kinds of piles were investigated by finite element method, which were Kanpan pile and Zhizhu pile. The results showed that the bearing capacity to resist drawing for Kapan pile was fairly higher than that for Zhizhu pile, however, the compressive capacity was similar to each other. Scientific understanding to pile and rock interface characteristics was the precondition for objectively evaluating rock-socketed pile bearing capacity. |
