【摘要】 在桩极限端阻力、极限侧阻力与标准贯入击数的统计模型以及剪切波速度与标准贯入击数统计模型的基础上,建立了常见土质条件下桩极限侧阻力、极限端阻力与剪切波速度的相关模型。应用瞬态面波测试技术可快速地获取地下不同深度的剪切波速度值,从而提出了应用瞬态面波预测摩擦桩极限承载力的新方法。模型桩试验分析及实际工程应用表明,该方法具有良好的应用前景。更多还原

【Abstract】 Based on the statistical relationships of the number of standard penetration test (SPT) with the standard value of utmost lateral friction (ksiq) and standard value of utmost tip resistance (pkq) of piles,and SPT number with shear wave velocity (sV),the interrelated models of sV with ksiq and pkqin the soil around pile is established. Using the technique of transient surface wave test,the shear wave velocity in different depth below the ground can be obtained rapidly. So,a new method of transient surface wave test technique is put forward to predict the bearing capacity of friction pile. Model pile essay and practical engineering application indicate that this method has favorable application foreground.更多还原
