水泥粉煤灰碎石桩复合地基在磐岭泵站工程中的应用

Application of Cement Fly Ash Gravel Pile Composite Foundation in Panling Pumping Station Project

通过对磐岭泵站工程地质条件和泵站常用软基处理方法的分析,选择水泥粉煤灰碎石桩复合地基对磐岭泵站进行软基处理。本文提出了水泥粉煤灰碎石桩复合地基设计计算的主要方法和施工质量控制要点。经复合地基载荷试验证明,水泥粉煤灰碎石桩复合地基在深厚软土地基上的泵站、水闸等类似工程中应用效果良好,值得推广应用。

Based on the analysis of the engineering geological conditions of Panling pump station and the common soft foundation treatment methods of the pump station,the cement fly ash gravel pile composite foundation is selected for soft foundation treatment of Panling pump station.The main methods of design and calculation of cement fly ash gravel pile composite foundation and the key points of construction quality control are put forward.The load test of composite foundation proves that the cement fly ash gravel pile composite foundation has good application effect in pumping stations,sluices and other similar projects on deep soft soil foundation,and is worthy of popularization and application.
