| 摘 要： | 利用广西南友路及湖南常张路的膨胀土土样,在不同的坡比和排水边界条件下,模拟积水、阴天、降雨和日照四种气候条件进行了九组室内模型试验,得到了在干湿循环作用下膨胀土路基中侧壁土压力和底层土压力的变化规律,为膨胀土路基的防、排水设计提供了非常有参考价值的试验数据.

| Abstract: | by using the expansive soil sample of NanYou Rosd and ChangZhang Road, nine group indoor experimentation was carried on, which simulated different combination of four kinds of climate of hydrops, overcast, rainfall and sunlight and four grade. The law of the side and bottom soil pressure change with time under the function of the alternation of dryness and wetness is concluded, which will offer valuable test data to the drainage and protection design in the expansive soil formation. |
