| 摘 要： | 为研究孔内深层强夯法中不同桩长对自重湿陷性黄土地基处理效果的影响,进行了3个相同桩间距、不同桩长,单位面积为20t的地表浸水载荷试验.试验结果发现:自重湿陷性黄土场地经过DDC工法处理后,浸水试坑中水分入渗十分缓慢;3个处理区域没有发生较大沉降,冻胀作用引起的地表隆起大于承台下降和土体湿陷引起地表沉降;3个不同DDC桩...

| Abstract: | In order to research the influence of the DDC piles with different depths in the treatment of self-weight collapse loess,the soaking load tests including three areas of same pile spacing and different pile depths were carried out.The tests indicate that after the treatment of collapsible loess by DDC method,the water penetrating into the loess is very slow,there does not appear the greater surface sedimentation in the treated areas,and the sedimentation due to loess collapsibility is greater than that due t... |
