Variable stiffness underground sequential wall fencing structure

The invention relates to the technical field of underground civil construction engineering, in particular to a variable stiffness underground sequential wall fencing structure. The variable stiffness underground sequential wall fencing structure includes an upper wall body and a lower wall body, the upper wall body comprises a transverse wall body and a longitudinal wall body which are connected into a whole, the transverse wall body is arranged on the side surface of the longitudinal wall body, and the lower wall is formed by the longitudinal wall body of the upper wall body extending downwards to protrude from the transverse wall body. The variable stiffness underground sequential wall is arranged to meet the fencing of different portions of stressed asymmetric abnormity alien shaped foundations, construction cost and construction difficultness are greatly reduced, and high economic and technical benefits are obtained.
