strength potential surfactant expansive swell



本文采用表面活性剂作为土壤固化材料,并辅以石灰,检测了固化土的无侧限抗压强度和无荷载膨胀量。结果显示表面活性剂可以降低土壤膨胀量,而加入石灰后的复配固化剂则更加有效地增强土壤的抗压强度,降低土壤的膨胀量,具备推广价值。


 












外文摘要





 



In this paper, the role of surfactant on swell potential and strength of expansive soils is investigated by unconfined compressive strength experiment and swell potential experiment. The results indicate that surfactant is effective to reduce the swell potential of expansive soils and that the stabilizers composed of lime and surfactant can enhance strength and reduce swell potential of the expansive soil significantly.
