It becomes more reasonable to define an interface during the numerical analysis and design calculations, the selection of the constitutive relation of the interface is directly related to the accuracy of the numerical calculation results. 1 Introduction The interaction of tunnel surrounding rock and supporting structure has always been the hot issue of tunnel engineering.
Research on contact mechanism of the interaction between the surrounding rock and the supporting structure in underground engineering [D].
GB50218-94 Standard for Engineering Classification of Rock Masses [S].

The one-stage project has been completed, and the second stage engineering will now proceed to be constructed.
Engineering is designed to be one floor basement, pit excavation depth of approximately 3.3m., length of 102m, and width of 75m.
The one-stage engineering is in the west side of the site, and there are no buildings and municipal pipelines nearby the site.

Computational Approaches for Good Alternative Solutions Based Load Resistance Capacity in Design of Steel Moment-Resisting Frames Byoung Han Choi1, a 1 Department of Civil Engineering, College of Engineering, Chonbuk National University, Jeonju, Jeonbuk 560-764, South Korea a han1020@hotmail.com Keywords: Cost Function for Steel Moment-Resisting Frame Design, Design Redundancy, Modeling to generate alternatives, GA-Based trade-off study.
In addition, the engineer may also wish to tinker with these solutions and arrive at a better solution.
Another parameter that an engineer may also consider is the number of different section types.
Therefore, engineers may also prefer Alternative.2 to the others.
