水泥土复合地基由于充分利用地方建筑材料,造价低,工期短和强度高,在工程中得到了广泛的应用。但水泥土的理论研究落后于工程实践,对水泥土施工中配合比、水泥掺入量和水泥土复合地基强度与承载力的确定等问题一直影响技术的发展和推广应用。通过工程实践分析总结了水泥土复合地基工程应用中的技术问题。 Cement-soil composite foundation due to make full use of local building materials, low cost, short duration and high strength, has been widely used in engineering. However, theoretical research on cement soil lags behind engineering practice. The problems such as the mix ratio in cement-soil construction, the amount of cement incorporated and the strength and bearing capacity of cement-soil composite foundation have been influencing the development, popularization and application of technology. Through engineering practice, the technical problems in the application of cement-soil composite foundation are summarized.
