The use of soft soil Shallow Large Span Tunnel and the Urban Design Study Cave + CRD method, that is, first excavated in the hole, and then has two main tunnel excavation outside the three-hole lead, followed successively by the main tunnel excavation in the left lane the inside wall of the three-hole lead, finally has the right line of the main tunnel excavation by construction technology inside the walls of the three-hole lead, materials and energy savings, effectively control costs and maximize social and economic benefits.
Beam overall state of compression, bending moment is small, in line with the theoretical analysis of the law, but its material properties play a limited, in contrast to shot Crete stress state, the proposed design phase should be appropriately reduced beam model, increasing jet concrete thickness, material properties, and give full play to project cost savings.

In recent studies, linear viscoelastic material laws combined with large-deformation theory were used to model brain tissues [17, 51, 52], except for the work of Mendis [53], who employed nonlinear viscoelastic materials under large-deformation.
A hyperelastic material was used for the brain to maintain these properties, in conjunction with a viscoelastic material property, giving the material a decay factor of β = 145s-1.

Inorganic encapsulation can greatly improve water resistance, but can hardly improve phosphors' compatibility with organic materials.
Organic encapsulation of inorganic powders can not only protect inorganic powders out of eroding by outer chemicals, but also increase their compatibility with organic materials [10-12].
In the present work, methylaminopropyltrimethoxysilane coupling agent (MAPS) and methylmethacrylate (MMA) were used as organic raw materials to encapsulate SrAl2O4:Eu 2+, Dy 3+ phosphors.
