| 中文摘要: |
| 结合现场试验，研究了高速公路夯实水泥土桩复合地基桩土应力比随路基高度及时间的变化规律。在路基填筑期间，桩土应力比并非常数，基本上在1.0～2.0之间变化。在荷载不变的条件下，随着时间的增长，桩土应力比随之增大，但变化幅度较小。该成果为类似工程设计提供参考。 |
| 英文摘要: |
| The rule of the pile soil stress ration of highway compacted cement treated soil pile composite foundation with the embankment height and time going is studied in this paper based on the test on site. During construction of the embankment, the number of pile soil stress ration is about 1.0～2.0. When the embankment loading keeps constant, the number of pile soil stress ration will increase slowly with time going. This conclusion can be useful for other similar engineering design |
