【摘要】 通过液塑限联合测定试验、击实试验、无侧限抗压强度试验，研究粘性土在不同灰比、不同龄期、不同外部条件下的液塑限变化、最优含水量和最大干密度的变化、无侧限抗压强度的变化规律，阐述生石灰对粘性土塑性、压实度、强度和稳定性的影响及作用机理，招导工程实践。更多还原

【Abstract】 This paper studied the changing regulation of cohesive clay in liquid limit and plastic limit, optimum moisture content, maximum for density and unconfined compression strength through liquid-platic united test, compact test and unconfined compression test under different ratio of lime, different curing period, and different external conditions. The lime infuence to cohesive clay on the plasticity, degree of compact, strength and stabilization, and the action mechanism of lime are described. Some suggstions are given to guide the construction of cohesive clay improved with lime-additive.更多还原
