ABSTRACT
The article considers low level convergence problem of bending moments in diaphragm wall is considered in this article. The article presents the main calculation methods that have become widespread in modern design practice. A comparative analysis of stress-strain state calculating results of a trench diaphragm wall for deep pit in the conditions of soil in St. Petersburg. To estimate the accuracy of the calculation methods, the calculation results were compared with the data of inclinometric monitoring in the trench diaphragm wall. At the same time, in order to be able to verify the obtained calculation results not only by the values of deformations, but also by the values of the calculated forces, a method for estimating bending moments in a trench diaphragm walls in the ground via inclinometric monitoring data is suggested. Comparative analysis of geotechnical monitoring data and various calculations showed high convergence with the results of the calculation, taking into consideration the possibility of excess pore pressure, nonlinear soil behavior and nonlinear rigidity of reinforced concrete.
