摘 要:
考虑到土性对水泥土强度的影响，提出了在软土中掺砂以改进水泥土抗压强度性能的方法。选取深港西部通道填海区含有机质的淤泥，采用均匀设计法来考察水泥掺入比、砂的掺入比、龄期和水泥土抗压强度的关系；建立了其回归模型，研究了3个因素对强度的影响情况，给出了优化配比的方法；最后提出了改进机具以实现水泥土掺砂的设想。[著者文摘]

Abstract:
Considering the influence of soil kinds on compression strength of cement-stabilized soil, an innovation method to increase the compression strength is proposed by adding sand to soil together with cement slurry, Silt samples came from reclaimed areas in Shenzhen western corridor. Uniform design was employed to analyze the influences of cement proportion, sand proportion and conservation age to compression strength. A regression model was founded. Using the model, the influences of the 3 factors to the compression strength were understood, and the method to optimize mixing prescription was illustrated, Finally, the idea which aimed to improve rig to make adding sand to soil possible, was introduced.[著者文摘]
Key words:
compression strength of cement-stabilized soil; test of mixing soil with sand; optimum mixing prescription
