Abstract: There is a large area of travertine in China. Scholars at home and abroad have done a lot of research on the formation and influencing factors of travertine, but the ecological restoration materials and techniques for geological cracks in travertine areas were seldom examined. The post-earthquake geological fissures in the Jiuzhaigou scenic area is taken as the research object. Combined with hydrological conditions and the properties of travertine particles, and on the basis of traditional glutinous rice mortar, this paper develops a kind of grouting material with excellent performance by mixing different proportions raw materials, modifier and certain graded travertine particles, and its fluidity, setting time, compressive strength and flexural strength are tested. The laboratory tests show that the material is characterized by good fluidity, controllable setting time, high strength and underwater casting. The indexes of specimens curing in air are better than those of specimens curing in water. The optimum mixing ratio of cracks restoration is 0.6~0.64 copies of glutinous rice slurry, 1.19 copies of gypsum, 0.29 copies of lime, 1 copies of travertine particles, 0.07 copies of modifier 1# and 1.19% copies of modifier 2#. The pumpable period of the slurry is 63~86 min, the initial setting time is 74~98 min and the final setting time is 92~125 min. In the field experiment of repairing cracks and strengthening cliff body in Jiuzhaigou, the modified glutinous rice mortar has achieved good results, reducing the water leakage from 50% to 3%, and recovering the waterfall landscape. The results show that the modified glutinous rice mortar is of good compatibility with travertine particles, which can improve the original pore structure of travertine particles, promote the growth of travertine landscape.
