Abstract: By analyzing of the existing methods for the neutral point of piling foundation, their features and applications are studied. The measured and predicted values are compared, and the various means are evaluated with engineering illustrations. The results indicate that the method of empirical value is the simplest and easiest one, but its predicted value is large. The gradually approaching method can be used under most conditions, but its forecasting process is complicated. The Japanese standard method and the theoretical approximation method involve more parameters, but their predicted values are more close to the measured ones.
