摘　　要：通过对龙游石窟砂岩胶结泥质中粘土矿物—蒙脱石的性质和结构特征;岩石中各类矿物在水中溶解度的变化;岩体与水反应的表面积,即岩石的孔隙率;与其相作用的水的化学性质,特别是水的pH值变化等方面的测试研究,证明被淹没在水下的石窟砂岩洞室相对较稳定。但洞室的水被抽干后,由于水环境的突变以及随后环境湿度的频繁变化,大大加速了洞室的风化。Researches have been done to find out the characters and the structures of the mineral in the clay of the sandstone, i.e. montmorillonite of the Longyou grottoes, to learn the different solubility of different minearal, to measure the surface area of the rock meeting the water（namely, the finestra ratio）, to find out the chemical character of the water which has the action with the rock, and particularly to test the pH of the water, so as to prove the caves under the water to be comparatively stable. However, when the water of the caves have been drained out, the weathering of the caves are accelerated causing the water environment and the humidity as well changed frequently.
