| 摘 要： | 膨胀土在干燥过程中由于失水收缩容易产生龟裂,裂隙产生后会极大削弱土体的工程性质.了解膨胀土在干燥过程中的抗拉强度特性,对从力学上进一步认识龟裂的形成和发展过程有重要意义.在室内配制了若干组初始饱和的膨胀土泥浆试样,当试样干燥到不同含水率时,利用改装的超微型贯入仪对试样开展了一系列抗拉试验,获得了膨胀土在干燥过程中抗拉强...

| Abstract: | Upon drying,desiccation cracks would occur in expansive soils due to evaporation and volume shrinkage.The presence of cracks may significantly weaken soil engineering properties.Better understanding the characteristics of tensile strength during drying is very helpful to study the essential mechanisms of desiccation crack initiation and propagation.In this investigation,Romainville expansive soil was used and several groups of initially saturated slurry specimens were prepared.The specimens were then dried ... |
