摘要
文章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。旨在为高速公路工程建设中提供准确并具有参考价值的复合地基沉降数值。
This paper interprets the composite loess foundation project.In view of the expressway composite loess foundation reinforced with cement and fly ash mixing pile,the settlement measuring cup method is adopted to carry out long-term survey work on this section.Finally,the settlement value and settlement velocity of cement fly ash mixed pile composite loess foundation with load and time are analyzed.Combined with the numerical value of the composite foundation in the actual construction site,the theoretical calculation and numerical model of the settlement value of the composite foundation are completed.The aim is to provide accurate and reference value for the settlement of composite foundation in highway construction.
