The paperw ork out the allow able w ater-supply: in m edian w ater period, the allow able w ater-sup- 3 3 p ly is 72300 m /d; and in the dry period, the allow able w ater-supply is 47600 m /d. When seepage w ells are used to exp loit w ater resources the inter-w ell interference is relatively small. Through the analy- sis of the smi u lation results of three differentw ater-supp lying projects( seepage w el,l galleries and large- diameterw ell), a conclusionw asm ade that the seepagew ell hadmany advantages compared to large-d-i ameterw ells or galleries in the study area, such as the lager reasonable yield, the h igher assuring rate and themuch less influence on local hydrogeological conditions
