摘要/Abstract

摘要：

通过无侧限抗压强度试验，分析了水泥改性泥浆（CMS）的应力-应变曲线、无侧限抗压强度（UCS）及弹性模量，并建立了CMS弹性模量时间效应模型。基于损伤力学，采用粒子群优化（PSO）算法识别随机场参数，建立了CMS细观随机损伤模型，并提出了随机场参数时间效应模型。结果表明：①CMS的应力-应变曲线为软化型曲线，水泥最佳掺量为20%，弹性模量与水泥掺量和龄期具有函数关系。②细观随机损伤模型能够描述CMS的应力-应变关系，并且随机场参数λ与养护时间具有函数关系。③通过损伤变量D与应变演变规律，能从细观随机损伤角度解释CMS宏观应力-应变特性。

Abstract:

Through the unconfined compressive strength test， the stress-strain curve， unconfined compressive strength， and elastic modulus of cement-modified slurry （CMS） were analyzed， and the time effect model of CMS elastic modulus was established. Based on damage mechanics， a particle swarm optimization （PSO） algorithm was used to identify random field parameters， a CMS mesoscopic random damage model was established， and a random field parameter time effect model was proposed. The results show that： ①the stress-strain curve of CMS is a softening curve， the optimal cement content is 20%， and the elastic modulus is a function of cement content and curing time. ②The mesoscopic random damage model can describe the stress-strain relationship of CMS， and the random field parameter λ has a functional relationship with the curing time. ③The macroscopic stress-strain characteristics of CMS can be explained from the perspective of meso-random damage through the damage variable D and strain evolution.
