Abstract Water is one of the most active factors causing the weathering of and salt damage to the surrounding rock of the cave. Experiments of liquid water adsorption(contact) and gaseous water adsorption(non-contact) on the support conglomerate of Mogao Grottoes at Dunhuang were carried out. The water absorption characteristics of and its influential factors to the conglomerate under two types of conditions were compared and analyzed. The influence of each factor on the water absorbing capacity of conglomerate under liquid and vaporous water conditions was quantitatively analyzed through the mathematical models of the water absorption rate of conglomerate under the different influential factors. The experimental results showed that，for two different conditions，the characteristics of water absorption of the conglomerate samely varied with the time. The double logarithmic curves of water absorption have an upward convex shape. The average water absorption of liquid water is 14.9 times higher than that of gaseous water. The influence of the kaolinite on the water absorption capacity has a negative correlation under the liquid and gaseous water conditions. Especially，the kaolinite has the greatest influence on the rate of saturated water absorption under the gaseous water absorption. The illite has a negative correlation with the water absorption capacity under the liquid water condition，but has a positive correlation under the gaseous water condition. The porosity has a positive correlation with the water absorption capacity under the liquid and vaporous water conditions，and has the greatest influence on the water absorption capacity under the liquid water condition.

Key words： rock mechanics Mogao Grottoes conglomerate liquid water absorption gaseous water absorption water absorption characteristics
