摘　　要：桩周摩阻力、桩底反力与位移和土质有关.通过桩的静栽试验和对桩周摩阻力,桩底反力测试,并对试验数据进行分析,获得了在复杂地质条件下,基桩的荷载传递特性,桩土作用特点,桩周摩阻力及桩底反力发挥特性.在此基础上评估桩的承栽能力,可作为在复杂地质条件下进行桩基工程设计和施工的参考.The frictional resistance around pile,the counter force of the pile bottom are related to the displacement and soil.Through the pile static load test and the test of the frictional resistance around pile and the counter force of the pile bottom,some conclusion in complex geological condition can be obtained by analysing the test data,which are the foundation pile＇s load transfer characteristics,the effect characteristics of soil and pile,the vertical bearing behavior and the side-friction characteristics of the foundation pile.The results,which are based on this assessment of the carrying capacity of pile,can supply references to the design and construction of foundation piles in the complex geological conditions.
