Currently, during the construction of tunnels of the Moscow Metro, a tunnel-boring mechanized complex with active face loading is used because of its ability to minimize the impact on the surrounding development. Nevertheless, a slight subsidence of the earth’s surface during tunneling develops even at a great depth in rocky soils. Additional movements of the soil in the direction of the face of the tunnel-boring machine can be predicted in several ways: empirical, analytical, numerical. The purpose of this work is to correct the outbreak ratio affecting the subsidence of the earth’s surface numerically in the PLAXIS software package for rocky soils using geotechnical monitoring data. The article considers the construction section of interstation tunnels with a diameter of 6 m of the Big Ring Line. The projected route is located mainly in limestone and marl (carboniferous deposits). The recalculation of the outbreak ratio according to the monitoring data of buildings, structures and infrastructure facilities of Russian railways was carried out in flat and spatial settings. On the basis of the results of the adjustment, the calculated range of the technological parameter under consideration, which mainly varies from 0.25 to 0.56% in a flat setting, and from 0.44 to 0.81% in a three-dimensional model, is established. In addition, the authors examined the tunneling section, where dispersed soils are developed in the upper part of the face of the tunnel-boring mechanized complex, and rock soils are developed in the lower part. In this case, the value of the technological parameter reaches 0.67% in a two-dimensional problem. In turn, it was established that there are sections in the territory under consideration with a outbreak ratio not exceeding 0.1%.
