| 摘 要： | 为研究大厚度自重湿陷性黄土湿陷变形规律,对自重湿陷土层36.5m的场地,进行直径40m的浸水试验。通过试验发现:浸水试验昼夜耗水量的变化规律基本上呈现先大、后缓、再稳定的趋势;场地中的地表沉降观测点的总湿陷量及沉降速率变化规律与深层沉降观测点的总湿陷量及沉降速率规律几近相同;大厚度自重湿陷性黄土场地湿陷变形规律呈现浸水期四个变化阶段和停水期两个变化阶段。

| Abstract: | For the research on deformation regularity of self-weight collapse loess with heavy section,a diameter 40m soaking test was carried out in a site of collapse loess with 36.5m depth.The test indicated that diurnal water consumption of soaking test appeared as the basic regularity which increased quickly in the beginning,then increased moderately,and lastly stabilized.Total collapse and collapse rate of ground and deep level observing point presented the same regularity.The deformation regularity of self weig... |
