对黄河冲（淤） 积粉土进行土质分析和生石灰粉稳定强度试验结果表明，由于该类土粘粒含量极少，粉粒含量高，粒度均匀，生石灰消解释放的热量不能为稳定土所充分利用，生石灰粉稳定土的强度较消石灰稳定土无明显提高，且生石灰粉稳定土造价较高，故工程中不宜采用根据该类土的土质特性，提出了二灰土外掺活性激发材料的稳定方法 The results of soil analysis and stable strength test of lime powder on the silt-filled silt soil of the Yellow River indicate that due to the low content of clay in this type of soil, the content of powder particles is high and the particle size is uniform. The heat released by lime decomposition cannot be a stable soil. With full utilization, the strength of lime stabilized soil is not significantly higher than that of hydrated lime stabilized soil, and the cost of stabilized lime soil is high. Therefore, it is not appropriate to use radon in the project. According to the soil characteristics of this type of soil, the activated lime-mixed active material is proposed. Stable method
