砂土液化砂土液化SandLiquefaction饱水的疏松粉、细砂土在振动作用下突然破坏而呈现液态的现象。其机制是饱和的疏松粉、细砂土体在振动作用下有颗粒移动和变密的趋势，对应力的承受从砂土骨架转向水，由于粉和细砂土的渗透力不良，孔隙水压力会急剧增大，当孔隙水压力大到总应力值时，有效应力就降到0，颗粒悬浮在水中，砂土体即发生液化。砂土液化后，孔隙水在超孔隙水压力下自下向上运动。如果砂土层上部没有渗透性更差的覆盖层，地下水即大面积溢于地表；如果砂土层上部有渗透性更弱的粘性土层，当超孔隙水压力超过盖层强度，地下水就会携带砂粒冲破盖层或沿盖层裂隙喷出地表，产生喷水冒砂现象。地震、爆炸、机械振动等都可以引起砂土液化现象，尤其是地震引起的范围广、危害性更大。砂土液化的防治主要从预防砂土液化的发生和防止或减轻建筑物不均匀沉陷两方面入手。包括合理选择场地；采取振冲、夯实、爆炸、挤密桩等措施，提高砂土密度；排水降低砂土孔隙水压力；换土，板桩围封，以及采用整体性较好的筏基、深桩基等方法。
