Variation law of water-earth pressure of deep excavations during construction process

The comprehensive understanding of deformation and mechanical behavior of retaining structures under water-earth pressures is of paramount importance for the design of deep excavations. However, there is a certain error between the measured and theoretical pressures. The error induced by various factors affects the security and stability of retaining structures. The Residential Square Station is a representative project of Wuxi Metro Line 1. The variation law of water-earth pressures during the construction process is studied through the analysis of the measured data. The results have guiding significance for similar projects in Wuxi.
