在室内基坑中对1根等截面管桩和2根变截面管桩进行单桩水平静载荷模型试验，对比研究两类管桩单桩水平承载性能方面的差异。试验结果表明：等截面模型管桩与变径比为0.57与0.71的变截面模型管桩的单桩水平的临界荷载依次为1.2,1.6,1.2 kN；单位体积水平承载力特征值依次为95,147，115 kN/m3。变径比为0.57与0.71的变截面管桩的单位水平承载能力比等截面管桩分别提高了55.1%和21.6%；变截面管桩变径比越小，单位水平承载能力越大；材料的利用率也越高。

Makes single pile horizontal static load model tests on an equal-diameter pipe pile and 2 variable-section pipe piles in the indoor foundation pit, and compares and studies their difference of horizontal bearing capacity. The results show that:the critical load of equal-diameter pipe pile and variable-section pipe piles of variable section ratio of 0.57 and 0.71 is 1.2, 1.6 and 1.2 kN, respectively;their characteristic value of horizontal bearing capacity per unit volume is 95, 147 and 115 kN/m3, respectively. The pipe piles of variable section ratio of 0.57 and 0.71 improve horizontal bearing capacity of 55.1%and 21.6%per unit volume respectively comparing to equal-diameter pipe pile;and the smaller variable section ratio of variable-section pipe pile is, the greater horizontal bearing capacity per unit volume is and the higher material utilization is.
