Vertical reinforcement earth dam is a new type of dam that has been increasingly applied in Sichuan Province in recent years.Its characteristic is that after the earth dam is filled,a concrete rigid structure similar to a cut-off wall is implanted vertically to work together with the shell material,maintaining the dam's stability and providing seepage control.The construction process of this dam type differs from that of traditional core wall dams,and its calculation must consider the nonlinear constitutive model of the shell rockfill material,the linear constitutive model of the longitudinal reinforced structure,the contact nonlinear constitutive model at the interface between the core wall and the shell material,as well as the simulation of the staged construction process-from staged filling of the dam to pouring of the longitudinal reinforced core wall and finally reservoir impoundment.
