Abstract:

一种适用于地铁车站砂土地基的抗液化方法属于地下工程抗震领域。其特征在于:在易于发生砂土液化的地铁车站开挖完成后在基坑底部设置1-3层级配均匀,耐风化的碎石或砾砂形成反滤层,每层粒径随水流方向增大。反滤层能在土层中形成良好的排水减压通道,加速超孔隙水压力的消散,使得在地震力作用下,难以聚集形成使土体液化的超孔隙水压力,从而可以防止砂土液化。进一步,1-3层反滤层根据太沙基原理计算每层反滤料的粒径。反滤层能起到滤土排水的作用,其渗透系数极大,在振动过程中反滤层体内的超孔隙水压力为零,水进入管道随即排走。本发明优点:材料易于取得,施工简单易行;不仅能起到碎石桩径向排水的作用,也有竖向排水的作用。
