本文根据近年来对软弱夹层工程地质的有关论述及部分实际资料,综述了关于软弱夹层的物质组成及分类;软弱夹层的分布规律;软弱夹层抗滑稳定分析方法;软弱夹层的处理方法等几个主要工程地质问题的研究现状。文中还较详细地介绍了桓仁、朱庄、双牌、葛洲坝等水利水电工程根据各自具体的工程条件和软弱夹层特性,所采取的挖、灌、排、截、锚等处理方法和措施,实践证明,这些方法是可行的,均达到了预期的效果。此外,文章不仅对上述的研究现状进行了初步分析,还对软弱夹层的研究方向提出了一些看法和建议。
Based on the related discussion and some actual data of soft interlayer engineering geology in recent years, the paper summarizes the material composition and classification of soft interlayer, the distribution of soft interlayer, the anti-sliding stability analysis of soft interlayer and the processing methods of soft interlayer Research Status of Major Engineering Geological Problems. In the paper, some methods and measures such as excavation, irrigation, drainage, cutting and anchoring are also introduced in detail according to their specific engineering conditions and the characteristics of weak interbed, such as Huanren, Zhuzhuang, Shuangpai, Gezhouba, Practice has proved that these methods are feasible, have achieved the desired results. In addition, the article not only makes a preliminary analysis of the above research status, but also puts forward some opinions and suggestions on the research direction of soft interlayer.
