| 摘 要： | 红层在四川盆地中广泛分布,随着大量基础工程建设项目的实施,红层岩溶问题日渐显现。而相对于红层岩体遇水易软化、膨胀等不良地质问题的研究,红层岩溶问题研究比较少。根据在四川红层地区多年的地勘工作实践,分析了四川红层岩溶具有非均一性、成层性、埋深大等特点,提出真红层岩溶、"假"红层岩溶等两种不同类型的岩溶形成机制。这些红层岩溶的分布特征和形成机制的提出,对这一地区的工程地质勘察、设计施工等工作有一定的指导意义。 |

| Abstract: | Red beds are widely distributed in the basin of Sichuan.Many basic buildings of railways and highways have been built in the red-bed zones in the past few years.The matter of the karst in red beds have been going up.However,relative to the ill geological researches of the intenerate and expansion in the encountered-water red beds,the karst matter in red beds have seldom been researched.On the basis of several years job-experiences in the red beds in Sichuan,the authors have analyzed that the karst in red be... |
