描述:埋设在土中的格栅受到沿其平面方向的拉力时,将在拉力方向上引起应力和变形。同时由于法向应力的作用,在格栅与土的上、下接触面上将产生阻碍格栅与土相对运动的摩擦应力,且其分布沿格栅埋深方向是不均匀的,施拉端最大,并随着水平拉力的增大逐渐向自由端传递。

影响土工格栅与膨胀岩界面力学特性的因素

土工格栅作为一种高强度的加筋材料,埋设于土中形成复合加筋土后,一方面可提高土体的强度,另一方面可以限制土体的侧向变形,近年来广泛应用于公路、铁路、水利、机场、市政等领域,有关加筋机理方面的研究也正引起国内外岩土工程界的关注。由于格栅的抗拉特性,当其埋设于土中并受到平面方向的拉力时,会在格栅内引起应力和变形,同时由于法向荷载的作用,格栅与土的上、下界面将产生阻碍其变形和运动的摩阻力。这种筋土之间的相互作用不仅表现在两种介质的界面(包括接触面和剪切带),而且在界面以外一定范围内的土体也参与了共同作用。这正是筋材加固作用的机理所在。
