摘要
污染地下水渗入大佛湾摩岩造像群，在石刻表面积聚可溶盐，加剧了石刻的侵蚀破坏，其中尤以泥质细粒长石砂岩风化剥落最为严重。研究渗水病害对石刻保护有重要意义。
All the statues in rock cave are located at Dafowan of Dazu County,Sichuan Province,inChina,Seeping through the polluted ground water,dissoluble salts are accumulated on the surfaceof the caved stone so that the erosion and destruction are stronly aggravated .Particularly,it isvery serious that some locations of clay fine arkose are wcathered and peeled.It will be of impor-tant significance to study on the disease of seeping water in order to protect the grotto.
