Study on the Reasonable Design Range of Cement Soil Cutoff Wall
With the development of science and technology, many new materials and new technology are applied to the dike anti-seepage project. The practical methods of foundation vertical anti-seepage technology include vertically paving plastic film technique, directional jet grouting method and cement soil cutoff wall technology. The concepts of cement soil cutoff wall and the anti-seepage projects task and principle were introduced is this paper. According to the geological conditions of the Lower Yangtze region, the application of cement soil cutoff wall technology to the embankment of the Lower Yangtze region were analyzed, and the influence of the cut-off walls permeability to seepage control effect was studied. It is concluded that the appropriate design of cut-off wall is permeability in an order of magnitude of 10-6 cm/s and the thickness is not less than 0.2m. The research results are helpful to the construction and design of dike anti-seepage project in future.
