摘要
总结了现有单桩竖向承载力检测技术存在的一些问题,结合实例提出了一种预测单桩承载力的间接方法———瞬态面波法。剪切波速与标贯击数之间也存在着相关关系,通过标贯击数建立起剪切波速与桩侧摩阻力及桩端阻力的相关模型,应用瞬态面波测试技术可快速检测桩周土剪切波速,确定单桩承载力。
The method for determining the load bearing capacity of pile is summarized and the basic principle of the transient surface wave test technique is described in this paper. The application of this technique to estimating the bearing capacity of pile, in particular, is presented with a practical example. The standard penetration test blow count (N(63.5)) related to the shear wave velocity could be used to estimate the bearing capacity of pile. The correlation model of Vs with qsik and qpk was constructed through N(63.5). The transient surface wave could be used to test the shear wave velocity of soil around the pile and estimate the bearing capacity of pile.
