| 摘 要： | 为评价红层岩土化学特性对工程的影响,对红层岩土pH值、EC值、碳酸钙、芒硝、石膏等关键物质成分的变化规律进行了试验研究,提出了岩土化学稳定性的工程概念与分析思路,初步建立了pH值、EC值、碳酸钙、芒硝、石膏临界含量等指标组成的红层岩土化学稳定性综合判别标准,将红层岩土分为化学稳定性强、化学稳定性中等、化学稳定性差三类,为红层特殊岩土定量化评价与分类治理提供了参考依据。

| Abstract: | In order to evaluate the chemical interaction degree between red beds rock and water, the properties of pH, EC, and some key materials are studied in laboratory; the idea of rock chemical-stability is advanced; the engineering criterion of red beds rock chemical stability is established, including pH, EC, percentages of key materials; according to the chemical stability criterion, the red beds rock is classified into three types: high chemical stability, middling chemical stability and low chemical stability; the chemical stability advice of quantifying evaluate and engineering design is provided for red beds projects. |
