摘要 目前常用的土壤固化剂(如水泥)加固软土时存在强度低、水稳性能差等不足,因此自制一种包含胶凝组分、碱性组分及表面活性组分的软土固化剂固化软土,并测试了固化土无侧限抗压强度、劈裂强度、水稳性能,其结果均好于水泥和商品固化剂A,且通过对固化土微观结构的观察,初步探讨了其固化机理,并研究了固化剂自身强度对固化土强度的影响。 When the soil is stabilized with common soil stabilizer (such as cement), the strength of stabilized soil is low and the water-stable performance is poor. So in this paper a new type of stabilizer was prepared with cementitous component, alkaline component and surface-active component, and unconfined compressive strength, splitting strength and water-stable performance were tested, the results indicate the effect of which is better than that of cement and commercial stabilizer A. Through observation of microstructure of stabilized soil,the stabilization mechanism was discussed preliminary and the effect of the strength of stabilizer on the stabilized soil strength was studied.
