| 摘 要： | 分析了负摩阻力发生的条件 ,比较了基桩荷载长期作用的实际工作状态与静载试验条件下荷载短时间作用的工作性状之间的差异 .分析表明在静载试验条件下基桩的负摩阻力是不可能发生的 ,指出常规的静载试验对于带负摩阻力基桩的评价是偏于不安全的 .通过一个实例说明了带负摩阻力基桩承载力的正确评价方法 ,并提出了设计与检测中的建议

| Abstract: | Occuring conditions of negative skin friction in pile were simply introduced.Comparisions of behavior of pile have been made between the working condition (longterm loading)and load-test condition(stimulate loading),which indicated that negative skin friction didn't exist in load-test condition and that ordinary load-test evaluation way was not safe enough for pile with negative skin friction.Based on the analyses of a case,reasonable evaluation way of pile with negative skin friction was recommended.Also,it may be a reference for civil engineer. |
