| 摘 要： | 灰土挤密桩因其施工速度快、造价低廉、施工设备简单、工期较短、能很好地消除黄土湿陷性,在处理深度要求适中、承载力要求一般的湿陷性黄土地基时得到越来越广泛地应用。以某电厂地基处理为研究背景,通过3种不同桩距灰土挤密桩试验效果对比分析,寻找最佳桩距,从而达到消除湿陷性、提高承载力的目的。 |
| 关 键 词： | 灰土挤密桩 挤密系数 桩距 湿陷性 |

| Abstract: | Lime-soil compaction pile has the advantages of fast speed,low cost and short working period in construction.It can eliminate the soil collapsible loess.It is applied more broadly in such kind of soil foundation treatment of general depth and bearing capacity.Taking the foundation treatment of a powerplant as an exam-ple,the test results of three kinds of lime-soil compaction pile with the different certer distance are compaired and analized in order to seek the optimatic certer distance of pile thus eliminating the soil collapsible loess and improving its bearing capacity. |
| Keywords: | lime-soil compaction pile compaction coefficient pile center distance collapsible loess |
