This paper no require simulate very large strain and change contact condition,and assume the brick masonry walls are uniform materials,hence,this paper adopt uniform three dimensions eight-node reduced integral entity unit C3D8R to scatter the model of T-shaped cross section brick masonry wall,and adopt three dimensions three-node truss unite T3D3 to scatter reinforcement.The model of 1.6FW is shown in Fig. 1.

Several challenges have been highlighted in recent publications like the contribution of residual color to single dye sorbate solutions of minimally prepared sorbent materials, the influence of pH on the shift in wavelength at which maximum absorption occurred.
Such spent lemon peel waste from which valuable food ingredients were extracted could also be an excellent source of biosorbent material.

However, coal tunneling project is a complex engineering influenced by many factors, related to all aspects of personnel, equipment, materials and environment, and it has a lot of technical process, bored by the geological conditions and natural climatic conditions.
This paper combined with the actual situation of the three coal lane tunneling projects through the references and selected 16 indicators to evaluate the safety situation of the coal lane tunneling project from the quality of personnel, equipment and materials, environmental conditions, safety management.
For the quality of personnel, the reference series and compared series were listed as: ； For equipment and materials, environmental condition and safety management, the reference series and compared series were listed respectively as: ； ； ； Determine the Difference Sequence Matrix of Each Sub-set.
For the equipment and materials subset, the sort of three coal lane tunneling project is: project2> Project3> Project 1, which means that the safety situation of project2 is the optimal, Project3 is followed, and project1 is the worst.
