- Abstract:
-
Many uncertainties in the rock and soil itself and the inhomogeneity of the excavation of the sunken well complicate the calculation of the force of the sunken well during the construction process. The mechanical analysis of sinking construction is carried out, a calculation method is proposed considering the ultimate bearing capacity of soil on the collapse surface of the edge foot during uneven excavation, and the dynamic model of sinking structure is established according to the Lagrangian equation of the dissipation function, and the engineering examples are used to verify that the established mechanical model can well predict the subsidence under a certain excavation amount.
