TEST RESEARCH ON THE BOTTOM SEAPAGE-PROOF DISPOSAL FOR CHANG AN MAN-MADE LAKE

The soil permeability is the property if water seapage in the soil, the research of which is the key to resolve problem of seapage proof for man-made lake .Though the in-site tests on peameabity of natural soil, disposed soil by deap compaction,the man-made compactected density lime soil .sement soil and plane soil the beter soil and parameter to protect seapage have been obtained .That provide the bases for seapage-proof disposal for the bottom of man-made lake.
