Prediction method for horizontal deformation of high-core-wall rock-fill dam in construction period

The invention discloses a prediction method for horizontal deformation of a high-core-wall rock-fill dam in a construction period, which comprises the following steps of: selecting a reference surface(generally a foundation surface) on the high-core-wall rock-fill dam, determining vertical distances from each monitoring point to the reference surface and the surface of the dam body according to the horizontal deformation monitoring points distributed in the dam body and the positions of the horizontal deformation monitoring points, and establishing a space coordinate system; determining the spatial position of each monitoring point; stress deformation and creep deformation of the deformation monitoring points in the river direction are calculated according to the horizontal deformation physical causes; calculating stress deformation and creep deformation of the deformation monitoring points in the transverse river direction; and according to the stress deformation and creep deformation of the deformation monitoring points along the river direction and the stress deformation and creep deformation of the deformation monitoring points along the transverse river direction, calculatingthe horizontal deformation of the deformation monitoring points along the river direction and the horizontal deformation of the deformation monitoring points along the transverse river direction.
