黄土地基加固而言,一般常用的处分方法主要是换填和抛石挤淤,该种处分方法工程量大、工期较长?费用比较较高。近几年来,采用土工合成材料处分软弱地基,已获得了较好效果。而用土工格室加固饱和黄土地基,则是一种新的加固方法。本文主要通过土工格室加固饱和黄土地基模子试验,考虑几种影响因素,对其地基性状和承载力进行分析探讨?/p> <p>  土工格室具有三维网格结构,整体强度高、耐老化、抗腐蚀性能好。用土工格室对饱和黄土地基进行局部换填加固,形成水平向加筋复合结构体,能进步地基承载力,达到加固饱和黄土地基之目的?/p> <p>  土工格室在黄土地基加固受力变形过程中,首先是土与填料的冲突与粘着提供了较大的冲突系数与粘聚力,产生了较大的冲突力和抗??其次是土工格室与充填于其中的填料共同工作?互相作用,土工格室对填料提供了较大的侧向约束力,格室侧壁对其中的填料产生了向上的冲突支承力,从而形成了一个具有较大刚度和强度的加筋复合结构层,起到了类似于筏板底子的作用,有效地分散了应力,使荷载的分布更为匀称?/p> <p>  在土工格室加筋黄土地基加固复合结构层中,若填料的压实度较低,将导致该结构层抗剪强度下降,从而制约了格室侧向限制力、格室侧壁与填料冲突力和地基土与填料冲突力及粘着力发挥,利于加筋复合结构层中滑动面的形成和发展,土工格室筏板底子的作用将会减小,从而降低其地基承载力?/p> <p>  土工格室加筋结构体中,格室对填料的侧向限制作用起主导因素,加筋体强度的进步主要表?为视粘聚力的增加,而内冲突角则变化不大,所以格 室填料类型对地基承载力有必然影响。由于格室的限制作用,对粗粒料而言,增加了一个附加粘聚力,使得土工格室中的粒料强度和刚度均比细粒土大,更能有效进步地基承载力,试验结果也介绍,土工格室为砂砾填料时,比黄土填料加固的地基承载力进?0%左右?/p> </div> </div>
