摘要
西宁石膏岩具有可溶盐含量较高,力学强度较低,在静水环境中被溶蚀的速度非常缓慢等特征,其环境水对钢筋混凝土结构有中等～强腐蚀性。以其作为水工建筑物地基,必须采取措施把石膏岩体与水体隔离起来。
Gypsolith in Xining is characterized by the high content of soluble salt,low mechanical strength,and a very slow solubility in quiet water environment and so on.Its en- vironmental water has a middle or strong corrosiveness to reinforced concrete structure. Therefore,it is necessary to cut the gypsolith body off from water mass if take gypsolith as the foundation of hydro-engineering building.
