补充资料：淤泥
在静水或缓慢的流水环境中沉积，经物理化学和生物化学作用形成的，未固结的软弱细粒或极细粒土。属现代新近沉积物。淤泥按粒度组成可以是粉土质的或粘土质的，细砂质或极细砂质的极少。海滨淤泥的粘土矿物以伊利石和蒙脱石为主，淡水淤泥则是以伊利石和高岭石为主。淤泥含有较多的(2～3％)和多的(10～12％)有机质，其含量随深度而减少。淤泥的主要特性是：天然含水率高于液限，孔隙比多大于1.0；干密度小,只有0.8～0.9克／立方厘米;压缩性特别高,压力自9.8×104帕增加到19.6×104帕时，压缩系数为a1-2>0.05，压力自9.8×104帕增加到29.4×104帕时压缩系数a1-3>0.1;强度极低，常处于流动状态，视为软弱地基。淤泥按孔隙比可再细分为淤泥（孔隙比大于 1.5）和淤泥质土（孔隙比为1～1.5）。淤泥的自然结构变化十分敏感，结构及其强度受力破坏后能自动复原，这就是所谓的触变性。淤泥不宜作天然地基，因为它会产生不均匀沉降，使建筑物产生裂缝、倾斜、影响正常使用。在淤泥上进行建筑时必须采取人工加固措施。如压密、夯实，用垂直砂井排水，加速淤泥固结。有时可采用柱基，或在建筑物上部采用适应于不均匀沉降的刚性圈梁，沉降缝等结构措施，以保证建筑物的稳定安全。
