摘　　要：我国的石窟研究遗址主要分布于西北干旱区。由于独特的自然条件,风蚀风化作用强烈,大批遗址已破坏严重。因而开展石窟遗址防风化加固和岩体裂隙灌浆研究十分必要。钾水玻璃(PS)是一种水溶性的无机胶结加固材料,试验证明经PS-C材料加固后的岩体强度成倍增长,耐风蚀能力、耐水能力明显提高。论文全面详尽地总结了PS-C材料加固石窟遗址技术,认识到PS-C是西北干旱地区石窟遗址加固的一种有效材料,可达到较理想的加固效果。There are many Grotto Sites in the arid region of Northwest china, and have been eroded and deflated under the specific climate and been damaged seriously. It is fairly necessary to study reinforcement of the grotto sites. Potassium silicate（PS） is and inorganic cementing-reinforcing material of aqueous solution. In this paper, a reinforcing technique for the grotto sites is described in detail and the experimental analysis involved indicates that the strength of consolidated soil by PS has widely been improved. Both its strength and Capability to prevent wind erosion and rain erosion have been enhanced. On the basis of our practice, we consider that the potassium silicate is an effective material for reinforcement of grotto sites in the arid Northwest China and has an ideal effectiveness. It should be put into practice in the future.
