摘要
对复合黄土地基工程进行解读,针对使用水泥粉煤灰搅拌桩进行加固处理的高速公路复合黄土地基,选用投放沉降量杯方式对该路段开展长期勘测工作。最终对勘测数据研究分析,总结水泥粉煤灰搅拌桩复合黄土地基沉降数值、沉降速度随荷载及时间的变化规律。与实际施工现场中复合地基数值结合,对复合地基沉降数值完成理论推算及建立数值模型。
This paper interprets the composite loess foundation project.For the highway concrete composite loess foundation using the concrete fly ash mixing pile,the long-term survey of this section is conducted by the way of placing the settlement cup.Finally,the survey data were studied and analyzed,and the change rules of the settlement value and settlement speed of the concrete fly ash mixing pile with load and time are summarized.Combined with the value of the composite foundation in the actual construction site,the theoretical calculation and numerical model of the composite foundation settlement value are completed.
