本文着重阐述了软弱夹层的物质组成、结构特性及其在长期渗水作用下的化学溶失作用和变化趋势。结果表明:构造作用和溶失作用,不仅是使夹层发生泥化(软化)的决定因素,而且也是给夹层的工程性质造成危害的重要原因。
This article focuses on the material composition, structural characteristics and chemical dissolution loss and change trend of the weak interlayer under long-term seepage. The results show that tectonic and dissolution effects are not only the decisive factor in mudding (softening) the interlayer, but also the important cause of the damage to the engineering properties of the interlayer.
