摘　　要：基于对已有软岩和软岩工程的研究方法、存在问题和软岩的物质组成、晶层结构与胀缩机理等的系统研究,提出了可以通过表面包覆改性实现物化型软岩工程稳定的新思路,并对物化型软岩的表面结构和性质进行了系统研究,给出了化学结构为Y-R-SiX3的有机硅化合物与物化型软岩表面反应的化学方程,为软岩和软岩工程稳定性的深入研究提供理论依据。On the basis of the systematized study on the available study methods and existing problems in soft rock and soft rock engineering, and on the material composition, layer-crystal structure and swell-shrink mechanism of soft rock, a new thought to realize the soft rock engineering stability by using coated surface modification method to improve the harmful properties of physic-chemical soft rock is put forwarded. The surface structure and properties of physic-chemical soft rock are studied systematically, and chemical equation of the physic-chemical soft rock surface reacts with organic silicon compound with the structure of YRSiX3 is obtained. This equation offers a theoretical foundation for the further research on soft rock and soft rock engineering stability.
