淤泥

The origin of glauberite attributes to various processes, including(1) direct crysllization from sulphate solution;(2) substitution of glauberite for gypsum;(3) transformation from hydrous glauberite; and(4) ion exchange between sodium sulfate and calcium-bearing mud.

钙芒硝的成因可归纳为：(1)直接从硫酸盐溶液晶出；(2)交代石膏成因；(3)从卤水中先沉积水钙芒硝后脱水变为钙芒硝；(4)硫酸钠溶液与含钙淤泥之间发生离子交换而生成。与菱镁矿紧密共生产出于海相地层之钙芒硝很可能形成于潮坪盐湖环境。

The strength reduction and the deformation incensement of supporting layer of the bases after saturated should be studied.

更多饱水后的强度降低率和变形增加率，当存在淤泥、软土、膨胀性土、湿陷性黄土等不良土层时，应进行相应的勘察试验工作。

The safety of the existing buildings should be decided based on the loading of the building, the foundation type as well as the buried depth of the foundation. The strength reduction and the deformation incensement of supporting layer of the bases after saturated should be studied. The corresponded investigations and tests should be carried out when silt, soft soil, expansive soil and collapsed loess et al exist in the bases.

对于现有建筑物的安全，要根据建筑物荷载、基础类型和砌置深度分类进行评价，研究了解地基持力层在饱水后的强度降低率和变形增加率，当存在淤泥、软土、膨胀性土、湿陷性黄土等不良土层时，应进行相应的勘察试验工作。
