摘要
针对国内外现有石灰改良膨胀土掺灰剂量确定方法上存在的不足,探讨了路堤膨胀土改良中石灰掺量的确定方法,明确提出确定掺灰剂量应遵循的原则,并据此原则提出以石灰土的加州承载比(CBR)值和CBR膨胀量作为确定最佳掺灰剂量的控制指标,为南友路石灰改良膨胀土提供依据,同时可用作其他地区石灰改良膨胀土路堤施工时的参考。
In allusion to the defect of the existing methods of determining the dosage of adding lime for lime improving expansive soil, the method of determining lime dosage is discussed ,and the following principles for controlling index of determining dosage of adding lime are specifically presented,and a new way that CBR value and the expanding amount of CBR can be used for the controlling index of determining the optimum dosage of adding lime is put forward ,and the gist is offered for lime improving expansive soil of Nan-You Highway. At the same time ,these fruits can be used as reference for other engineering practice of lime improving expansive soil.
