本文描述论敦粘土中装设有许多测量仪器的桩的现场试验。以沿桩身的有效应力和总应力的测量来分析加载试验过程中,桩的设置效果、地基平衡期和桩的承载能力。在很多方面,桩的性状不同于目前理论所预测的结果,特别是,加载速率对桩的摩阻特性有出乎意料的很大影响。 This article describes field tests of piles with many measuring instruments in Ondun Clay. Based on the measurement of the effective stress and total stress along the pile body, the setting effect of the pile, the foundation balance period and the bearing capacity of the pile were analyzed during the loading test. In many respects, the behavior of the pile differs from the results predicted by current theories. In particular, the loading rate has an unexpectedly large effect on the frictional resistance of the pile.
