Abstract:

In order to search for suitable structures of relief well for Dongting Lake region, the decompression effects of geotextile tied holey plastic tube, steel tube, sand filtration and no-sand concrete were analyzed through laboratory tests; and then suitable filter structures of relief well have been tested for Dongting Lake region Hejiadi Relief Well Project. The results indicate that the plastic blind drain and capillary plate relief well are suitable for the seepage control of Dongting Lake region.

Key words: Dongting Lake region, dike, relief well, filter layer, clogging
