Coated modification of physic-chemical soft rock and its mechanism

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.
