| 摘 要： | 为了研究独立柱基础在荷载作用下的受力特性,进行了4组不同条件的模型试验,测试了桩身应力,并获得4条完整的p-s曲线,以及不同位置的桩身摩阻力曲线.根据试验结果,分析了独立柱基中桩的受力特性,认为桩身摩阻力的发挥随位置的变化而不同,从而不同位置的桩发挥的作用大小不同;载荷板下土层的压缩主要在一倍边长范围内,桩身摩阻力较大处在上部1/4～1/2处,减小后在下部1/4处又变大.在载荷板面积不变的情况下,桩距小的极限承载力较桩距大的极限承载力大.

| Abstract: | Four model tests were carried in order to study the mechanical characteristics of piled isolated foundation.The soil resistance under the cap,the shaft resistance and the tip resistance of the piles were measured by installing various measuring gauges.Four integral p-s curves were also gotten.According to these test results,the piles in piled isolated foundation act different function factors at different stations.Under load board soil layer is compressed mainly in a range of one-time side length,the bigger... |
