Method for calculating horizontal displacement of underground diaphragm wall caused by foundation pit excavation
The invention belongs to the technical field of civil engineering, and particularly relates to a calculation method for horizontal displacement of an underground diaphragm wall caused by foundation pit excavation. At present, related theories for calculation of stress deformation of the underground diaphragm wall related to the non-limit soil pressure are still in the stage of engineering experience or finite element trial calculation, the underground diaphragm wall serves as a simply supported beam, and the horizontal displacement generated by the underground diaphragm wall under the combined action of the non-limit soil pressure and supporting axial force is solved through a force method. The method comprises the steps of constructing a mathematical model, and dividing and calculating sections according to a certain distance; assuming that the underground diaphragm wall is a simply supported beam, respectively calculating the horizontal displacement of each calculation section of the underground diaphragm wall under the independent action of the non-limit soil pressure, the non-limit passive soil pressure and the supporting axial force; and constructing an equation of horizontal displacement generated by the underground diaphragm wall under the combined action of the non-limit active soil pressure, the non-limit passive soil pressure and the supporting axial force by utilizing a force method, and solving to obtain the horizontal displacement corresponding to each calculation section of the underground diaphragm wall.
