| 摘 要： | 第三系红层中石膏分布比较广泛,大量的实验证明,石膏发生溶蚀的主要是含Ca2 的物质,并且溶蚀速率和与水接触的方式以及水头压力大小有直接关系。结合现场资料,将渗透系数K=10-5cm s作为石膏在第三系红层泥岩封闭下发生溶蚀的判据。同时针对水利工程中石膏溶蚀以及对砼的腐蚀性提出了相应的防治措施。

| Abstract: | The gypsum in Neogene red clay is extensive. Based on much of experiment, it can be known that the most material is the matter with Ca~(2 ) in process of gypsum dissolution, while the dissolution velocity lie on the contact means with water and the water pressure. According to the field data the conclusion is to take osmotic coefficient K=10~(-5)cm/s as the criterion of dissolution of gypsum closed in Neogene mud-stone. At the same time the corresponding measures to dissolution of gypsum and erodent character to the concrete in the hydro-engineering are put forward. |
