流砂层
quick sand bed
密切关系。流砂层岩性特征是，般砂粒粒度均匀孔隙度大、上下岩层多为不透水性。故常饱含地下水;粘土质流砂层具触变性，即受机械振动而液化，振动停止后又恢复原状;天然流砂层湿而带腐臭味。形成流砂的原因:吃l、山于地下爆破或机械震动的影响.在足够大的动水压力或动荷载作用「，层中水力坡度增大，流速增大，冲动细颗粒而使其悬浮和流动成渗透流砂(助由土粒周围附着亲水胶体颗粒，饱水时胶体颗粒膨胀·在渗透水作用下而悬浮流动;其流动速度有快有慢遇到以溃决形式急剧流动时，破坏力很大，会使地基和「_程的稳定性遭到严重破坏。流砂层它是矿山采掘作业的 ，大灾害其防治方法有疏干排水、灌浆固结、板桩加固等 (李远鄂陈国洗l一ushoeeng流砂层(quiek sand bed)埋藏于地下饱含水的，当工程揭露时引起渗透水流作用而发生流动的粉砂、细砂、亚粘土层。流砂层不仅分布于第四纪地层中，而且在基岩古老时代的地层中也有存在，它埋藏于不同的深度，其分布位置多与古河谷和近海冲积平原有
