【 摘 要 】

There is calculation method of basic parameters of linear-extended anti-filtration structures taking into account the initial filtration gradient of the filling material of "wall" in two cases. The first one is that the "wall" is defective type and it overlaps water-yielding heavily filtrated stratum with embedment into the second weakly filtrated stratum. The second one is the particular case of the decision of the common task and is the most effective. The second "wall" is a "wall" of a higher kind with embedment into an aquitard. The offered calculation method bases on the model which takes into account the non-linear way of water filtration through the "wall". It lets to avoid the inaccuracies in calculations. The water filtration through the "wall" will take place when the excess gradient exceeds the initial gradient. The calculation method, described in regulatory documents, doesn't take into account the initial gradient value. It influences on the choise of "wall" construction parameters. Taking into account the initial filtration coefficient lets to increase the calculations accuracy of anti-filtration structures. If the initial filtration gradient value is neglected, the calculation result from the obtained formulas for particular case will coincide with values, obtained by formulas, described in regulatory document.
