标准贯入试验（Standard Penetration Test，SPT）中的N-value（N值）是锤击数，是在标准贯入试验中，将一定规格的贯入器打入土层一定深度所需击打的次数。
The N is critical liquefaction SPT value;the N_0 is the reference value of SPT for given earthquake magnitude,peak horizontal acceleration,p. N是临界液化锤击数;N0是给定震级、加速度、概率水平、土层埋深和水位的标准贯入锤击数基准值;α为土层埋深水位修正系数,是埋深的非线性函数;β为基准值震级修...

To meet an inspection requirement for a deck footing, I need to convert an SPT N value to lbs/sqft to calculate the numebr and area of footings I need on some marginal soils. Is there a simple formula to compute SPT N values to allowable load /sq ft for the footings?
