| 摘 要： | 分析计算黄骅电厂新近吹填软土的真空预压模型槽试验过程数据,结果表明:该软土在真空预压80 kPa荷载作用下,经过150 d的排水固结作用,尽管应变固结度达到90%以上,能够有效消除残余沉降,但应力固结度较低,不足50%,土体的强度较低。

| Abstract: | Laboratory tests were conducted to improve the soft soil of newly dredged fill with vacuum preloading method.The vacuum load in the tests was 80 kPa.After drainage consolidation of 150 days,the strain consolidation degree reached more than 90% and the residual settlement was reduced effectively.But the stress consolidation degree was less than 50%,and the strength of soil after treatment was low. |

| Keywords: | soft soil theoretical calculation consolidation degree strength |
