摘要
本文简述了砂衬桩的结构形式,较细地分析了结构形式给承载力带来的好处。经过初步分析研究并结合两种施工工艺的砂衬桩试验结果认为:砂衬桩是一种典型的摩擦桩,比一般灌注桩可省材料费用30%～50%,混凝土使用效果可提高1～2倍;具有较好的抗震性能。
This paper briefly reviews the structure pattern of sand lining pile and minutely analyzes the benefit
which the structure pattern brings to the bearing capacity. According to a preliminary analysis
and study together with the testing results on the sand Lining pile constructed by two kinds of
construction techniques, this sand lining pile is considered as a typical friction pile. In compari-
son to the ordinary cart-in-place pile, it can save the material expense about 30%-50%, en-
hance the utilization effect of concrete about 100%~200% and possesses better anti-seismic
properties.
