桩基设计中静探指标的应用

Application of Indices of Static Sounding to the Design of Pile Foundation

本文对国内常用的利用静探指标计算单桩极限承载力公式中的系数α、β等指出了不足之处;对桩端阻力的计算方法提出了不同的看法,并给出了相应的修正系数;对计算精度的影响因素作了初步探讨。

The shortcomings of coefficients α、β in the formula, which is often used in China to calculate the ultimate carry capacity of single pile by using static sounding indices, are pointed out in this article. Different views on the calculation of pile end resistance and corresponding coefficients of revision are also proposed, an Initial study on factors which may influence the accuracy of calculation is conducted.
