摘要
通过对软粘土地层中的钻孔灌注桩进行静载荷试验 ,测试并分析了桩顶的荷载～沉降特性以及桩身轴力的发挥过程 ,并结合测试数据就桩身压缩变形与桩顶沉降的关系、规范法中综合系数ξ的取值以及桩身压缩变形分布规律等方面进行了计算与探讨 。
Based on static loading tests on bored piles in soft clay,the load-settlement curve and the characteristics of shaft force transfer are tested and analyzed.Through the testing data the relationship of pile shaft compression and tip settlement,the distribution of pile shaft compression and the appropriate value of the integrated coefficient in code method are calculated and discussed.
