摘要
随着沿海软土地区深基坑工程的发展,深度超过50m的超深三轴水泥土搅拌桩技术成为深层承压水控制的有效措施。通过工程实例介绍了超深三轴水泥土搅拌桩技术及其在深基坑工程中的应用情况。阐述了超深三轴水泥土搅拌桩的施工工艺、施工要点和质量控制措施,结合上海和天津地区的超深三轴搅拌桩的工程实例进行了说明,验证了超深三轴水泥土搅拌桩技术的可行性和可靠性。
As the development of the deep excavation engineering in the coastal soft soil area,the technology of ultra-deep triaxial cement-soil mixed piles more than 50 m in length has become the effective solution to control the deep confined water.The technology of ultra-deep triaxial cement-soil mixed piles and its application in deep excavation are introduced based on the practical engineering.The process of construction,key point of construction and the quality control measures of the ultra-deep triaxial cement-soil mixed pile technology are described.The successful application of the technology in Shanghai and Tianjin areas shows that the technology of ultra-deep triaxial cement-soil mixed piles is feasible and reliable.
