| 摘 要： | 负摩阻力问题广泛存在于桩基工程中，对承受竖向荷栽负摩阻力基桩开展静栽试验研究，具有重要的理论与工程实际意义。首先分析了负摩阻力发生的条件，比较了静载测试桩与工程桩工作性状之问的差异，给出了负摩阻力对桩基承载力和沉降影响的验算。通过实例说明了带负摩阻力基桩承栽力的正确评价方法，并提出了设计与检测中的建议。

| Abstract: | As it has long been recognized that,negative skin friction resistance most possibly exists on piles when the soil around pile move downward relative to the pile,so to studies on load-test of vertical loaded pile with negative skin resistance are of important theoretical and practical significance in engineering.Occuring conditions of negative skin friction in pilewere simply were first discussed. Comparisions of behavior of pile have been made between the working condition(longterm loading)and load-test con... |
