全套管灌注桩竖向承载性能及其预测研究

Research on Vertical Bearing Behavior of Benoto Cast-in-place Pile and its Prediction

为了了解全套管灌注桩的承载性能,在一施工现场对桩基进行了静载荷试验,得到了一些试验数据和Q-S曲线。经过对试验中得到的有代表性的Q-S曲线进行分析研究,可知这些Q-S曲线具有明显的双曲线特征,据此建立了一种全套管灌注桩承载性能预测的新方法。

In order to get to known the whole bearing behavior of Benoto cast-in-place pile, some static load test was done in construction site, with some test data and Q - S curves obtained. Analysis of the representative Q - S curves obtained from field static load test for Benoto cast-in-place pile, shows an obvious hyperbolic characteristics for Q -S curves. Based on this result, a new method to predict the bearing behavior of Benoto cast-in-place pile was developed.
