摘要
土工格室作为一种新型柔性防护材料,在公路防护中的应用十分广泛。室内冲刷模型试验表明,在黄土边坡中添加土工格室后,可以降低平均累计冲蚀率达48%,并可减弱冲沟的发育和形成,从而防止路基的坍塌;在饱和黄土地基承载力试验表明,在加土工格室后,可以将其承载力提高2～3倍,并使其破坏方式只有局部剪切破坏和整体剪切破坏2种。
As a type of new flexible protective material,geocell has broad application in slopes of highway.Eroding model experiment shows,by adding geocell,not only can the total average erosion rate be decreased to 48% but also gulches development and evolution are weakened,thus the collapsing of roadbed is avoided.Foundation bearing capacity of saturated loess test indicates,by the same way,that loess slopes of highway will double or treble its capacity and limit its failure to local or slobaal shear failure.Many practical engineering examples have proved,as a type of flexible protective materialt,hat geocell has good effects on slopes of highway.
