| 摘 要： | 目前 ,不同工艺的后压浆钢筋混凝土灌注桩已经广泛推广使用 ,其效果一般很好 ,使基桩的单桩承载力得到比较明显的提高。但是桩端压力究竟应该取多少为宜 ,往往还是靠经验确定。本文提出一种计算模型 ,为确定桩端压力提供了科学估算的依据。文中还分析了影响桩端极限压力的各种因素 ,可供进行压浆桩设计时参考。

| Abstract: | RC cast|in|place piles by grouting with different technologies are widely used currently with satisfactory results.The bearing capacity of single pile is enhanced distinctly. The value of pile tip pressure can only be determined according to experiences. A calculating model is proposed herein to provide a scientific basis for determining pile tip pressure. Various factors which may affect the ultimate pile tip pressure are also analyzed herein for reference of designing. |

| Keywords: | grouting pile ultimate pressure ratio of strength of modulus |
