中文摘要：

软岩的崩解、泥化往往给工程带来困难和损失。崩解、泥化实际上是岩体失水-吸水-膨胀的过程，水在这个过程中起着关键性的作用。硅烷偶联剂一树脂涂料中由于硅烷偶联剂在岩体表面和树脂问的架桥作用，使得涂层具有吸附牢固、疏水性好的特点，起到了阻止岩体与外界水分交换、加固岩体的作用。硅烷偶联剂一树脂涂料在软岩工程方面有着广阔的应用前景。

英文摘要：

The disintegration of soft rock often causes great difficulty to engineering. In fact, disintegration is a process of soft rock＇s dehydration, absorbing water and expansion. Water acts as the key in that process. The mixture of silane coupling agents and resin that is bridged with soft rock by silane coupling agents could reinforce soft rock, stop soft rock exchanging water from the air. The adsorption of the paint coat on soft rock is firefly, and that paint coat＇s hydrophobicity is good. Silane coupling agents and resin coud be used on soft rock in the days to come.
