| 摘 要： | 在控制含水量的前提下,对分别掺入不同量石灰、不同量水泥改性膨胀土试件进行强度和膨胀量试验,得到不同含 水量及不同石灰(水泥)掺量对改性膨胀土强度和膨胀性的影响,通过对实验所得数据的分析,找出含水量和掺石灰(水泥)剂 量的最佳融合点,并据此对膨胀土路堤填料的改性施工提出了一些有益的建议。

| Abstract: | This paper presents experimental shearing and swelling results of the modified expansive clay with different water contents and lime (cement) content. The influence of the water content and the lime (cement) content on the shearing strength and swelling capacity are evaluated according to the experimental results. The optimal water content and lime content are then obtained. The authors also provide guidelines for modification of expansive clay. |

| Keywords: | Expansive clay Shearing strength Swelling capacity |
