摘要
摘要:流变是岩盐类软岩的一种常见力学行为,其蠕变损伤破坏是岩盐的主要破坏形式之一。为此对四川盆地自流井构造大山铺、万家桥、大坟堡三种岩盐进行了蠕变试验研究。同时分析了两种岩盐蠕变损伤差异的原因,得出了两种岩盐蠕变损伤破坏形式为张性拉裂破坏,在大安制盐有限公司的大坟堡岩盐矿体提捞式淡水溶盐采卤和大山铺岩盐矿的高压注水采卤过程中均得到同一结果。
Rheological phenomenon is a common dynamic action with its creep damage being one of the major damage types of rock salt.Experiment and study are conducted on the three kinds of rock salt from Dashanpu,Wanjiaqia and Dafenbao in Ziliujing Structure of Sichuan Basin and reasons for difference between the creep damage of the two kinds of rock salt are also analyzed.It is concluded that creep damage of the two kinds of rock salt is of tensile rupture failure type.The same result is obtained in the extraction of rock salt brine by lifting process with fresh water in Dafenbao Rock Salt Deposit and brine extraction with high pressure water injection in Dashanpu Rock Salt Mine of Da′an Salt Making Co.,Ltd.
