The interface between soil and tunnel structure in two-dimensional model

HI STKOļ¼
Thank the stko official for giving a forum to discuss issues. i want to ask a question about ssi contact
I built a two-dimensional model, which is a box tunnel buried in the soil
Because it is necessary to monitor the pore water pressure in soil under dynamic load, I use quadup element to simulate soil
However, since the quadup unit is 3DOF and the structural unit is 2DOF, I cannot use zerolength element to connect the soil and structure, and I do not want to directly consolidate the soil and structure with equalDOF
Is there any good method to simulate the contact between soil and structure
best wishes
teddy
