| Abstract: | | 1. | The prefabricated cutoff wall as one of the economically justified designs can be regarded as the main watertight element of an earth dam. | | 2. | The cutoff wall can be made from precast asphaltic concrete and concrete blocks and combined — from both joined together on asphalt mastic. An analysis of the stress-strain state showed that each of these walls has a sufficient margin of deformability. | | 3. | The cutoff wall of precast concrete blocks, eliminating the use of asphalt for its construction and having a practically unlimited margin of deformability, can be of interest to designers and builders. |
