摘    要:本试验以水泥和粘土为主要原料,将粉煤灰和玻璃纤维掺入到水泥土中,通过室内三轴试验,得到水泥复合土的应力应变曲线。通过对实测的应力应变曲线分析可知:水泥复合土的应力应变曲线呈软化型,存在明显的应力峰值点,可将其分为:弹性变形区、塑性变形发展区、应力衰减区、残余强度区四个发展阶段。与此同时,通过对水泥复合土试件破坏过程的分析发现:水泥复合土的破坏形式为脆性剪切破坏和胀裂破坏。

关 键 词:水泥复合土  三轴试验  应力应变曲线  破坏特征

Abstract:In this experiment,the main raw material of cement and clay,fly ash cement and glass fibers incor-porated into the soil,through laboratory triaxial tests,the stress-strain curve obtained cement composite soil. Through the measured stress-strain curve analysis:Stress-strain curves showed a softening of cement compos-ite soil type,there is an obvious peak stress points,which can be divided into:elastic deformation zones,the development zone of plastic deformation ,stress relaxation area ,residual strength zone four stages of develop-ment.At the same time ,through the cement composite soil specimen failure process analysis found:cement composite soil damage in the form of brittle shear failure and bursting destruction .
Keywords:cement composite soil  triaxial test  Stress-strain curves  damage characteristics
