水泥稳定土基层强度变异性影响规律研究

对指定的石灰岩碎石,采用规范建议的级配,分别加入不同剂量的水泥,在不同的压实度条件下成型试件,分别在不同温度条件下对试件养生,然后进行7d无侧限抗压强度试验,并对结果进行分析。分析认为,压实度对抗压强度影响较大,保证施工规范要求的压实度是保证抗压强度的重要手段之一,而通过增加水泥剂量的方法增加抗压强度并不是一个好方法。

Variation Rule of Cement-Stabilized Soil Base Strength

Adding various content of cement into appointed limestone gravel with propositional gradation of criterion,the samples are molded under various degree of compactness and cured in various temperatures.Through 7d unconfined compression strength test,the result shows that compactness has great influence on compression strength,ensuring the compactness degree requested by construction criterion is an important measure to ensure compression strength,and it is not a good method that increasing cement content to e...
