Abstract：Inorderto improve the water storage efect of water conservancy projects，metakaolin wasusedas a clay materialand compounded with hydroxypropylmethylceluloseand Tianjing vegetable gum to preparecellulose/clayanti-leakage materialsandvegetable gum/clayanti-leakage materials，and their properties were studied.Theresultsshowed that theaddition of hydroxypropyl methylcellloseand vegetable gum totheanti-leakage materialscould increase their particle size and make them have the ability to prevent leakage.When theanti -leakage materials were prepared with 0.6% cellulose and 1.0% vegetable gum，the water seepage rate was basically 0.00% at 900 h，and the water quality was good for30 days.The pH valueswere7.20and7.28，the CODMn were 3.315and2.744 mg/L，the ammonia nitrogen contents were 0.352andO.375mg/L，andtheturbiditywere2.241and2.018NTU，respectively.Moreover，the3O-daystorage water quality reached the relevant national standards，and the storage efect was beter than that of HDPE geomembrane， which has certain potential value in the application of water conservancy engineering.
