摘　　要：利用波动方程理论建立嵌岩桩的动力分析模型 ,并通过 12根桩的CAPWAP分析 ,探讨了嵌岩桩的桩侧阻力和桩端阻力的承载特性 ,通过合理地选择动力分析参数 。Based on wave equation theory,a dynamic loading model is used to analyze the behaviors of rock\|socketed piles.The results of dynamic loading tests are analyzed by CAPWAP.According to the analyzed results of twelve dynamic loading tests on rock\|socketed piles,the behaviors of shaft resistance of the socket and toe resistance are discussed,a relationship of shaft resistance of socket to the length of socket and the rock strength and the construction of piles is presented.And the parameters of dynamic loading tests are estimated.Some suggestions for dynamic loading tests of rock\|socketed are made to analyze the bearing capacity.
