摘　　要：结合人防工程抗拔桩的静载荷试验,通过在沿桩身长度范围内土层分界面附近安装钢筋计,测得了桩身每段分担的荷载,研究了粘性土中抗拔桩荷载传递特征。利用相关规范中桩基抗拔承载力的公式对桩的承载力进行计算,并与试验结果进行了验证。Combined with static load test of uplift piles in air defense project, the load shared on each section of pile is measured with reinforcement meter mounted near soil mass boundary within pile length, and load transfer characteristics of uplift piles in clay soil is studied. The bearing capacity of pile is calculated using the formula of pile foundation uplift bearing capacity in relevant criterion and verified with test result.
