en Optimal design Optimal design پژوهشي Research <p>In this paper, a systematic approach is presented for optimal design of tunnel support lining using two-dimensional finite element analysis models of soil-structure interaction developed in ABAQUS software and the Modified Colliding Bodies Optimization (MCBO) algorithm implemented in MATLAB environment. This approach is then employed to study the influence of variable geometrical and geo-mechanical parameters on the optimal design of a class of practical access tunnels.</p> optimization, access tunnel, tunnel support, MPSO, ABAQUS, MATLAB. 339 354 http://ijoce.iust.ac.ir/browse.php?a_code=A-10-66-143&slc_lang=en&sid=1 H.
