[摘要] 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。

Abstract: The cement-soil composite foundation has been widely used in engineer due to full use oflocal architectural materials, low cost, short time and higher intensity. But the theory is behind the engineering practice. The problems such as the scale of soil-cement nuxing, the cement quantity, the intensity of cement-soil composite foundation, the bearing capacity and the determining method of strength of composite foundation strength, affects the develop of the technique. Based on the engineering practice of cement-soil analyses, some conclusions were presented.
Keywords: cement-soil; composite foundation; bearing capacity
