ABSTRACT
This article reveals various methods of accounting for retaining berm in the calculations of the slurry wall construction. For one calculation case, the calculation results were compared using the basic approximate methods for estimating passive pressure when installing ground berms. To validate the existing approximate methods, method of characteristics in limit equilibrium method (LEM) was developed, allowing us to obtain a mathematically rigorous solution. The result of the work is a graph of the distribution of passive pressure along the slurry wall construction. The proposed rigorous mathematical method showed high convergence with the CPM method. The suggested approach allows us to obtain characteristic zones of the structure where the passive pressure formed by the soil berm works.
