摘要
对江苏222省道南徐路拓宽改造工地现场的膨胀土进行干湿循环的试验研究,包括直剪试验和无侧限抗压强度试验,分析了试验数据,从而得到膨胀土随干湿循环强度的变化规律,可为实际工程需要提供可靠的数据。
Wetting-drying cycle in expansive soil is studied by experiments,and the expansive soil is borrowed from construction site of widening alteration of Jiangsu No.222 provincial road.The experiments include direct shear test and unconfined compressive strength test.Through analyzing the experimental data,the change law of expansive soil with the strength of wetting-drying cycle is found out.The experiments can supply the reliable data for practical engineering.
