Abstract: A full probability-based seismic risk analysis method for a tunnel under fault dislocation comprises: evaluating a magnitude-frequency relationship of a fault; obtaining a probabilistic seismic risk curve of a fault dislocation; calculating a series of bending moments of a tunnel lining under different fault dislocations; obtaining a series of damage index values RM of the tunnel; obtaining a vulnerability model of the tunnel damaged by fault dislocation; calculating a probabilistic risk that the tunnel crossing the fault is damaged due to the dislocation of the active fault; obtaining a probability P that the damage state is equal to or higher than a certain damage state within a specified period; and using the results to guide the assessment of the seismic risk of the tunnel crossing the fault. Modeling and analysis can be performed according to the actual situation of the tunnel crossing the fault with different factors.

Abstract: A two-stage energy dissipation type shed tunnel support structure connected by a principle of Dougong and a design method thereof are provided. The two-stage energy dissipation type shed tunnel support structure includes a Dougong joint domain, crossbeams and columns. The Dougong joint domain includes section steel members, wavy-wall cylindrical elastoplastic buffers, U-shaped sliding connecting troughs and high-strength bolts. Multiple layers of the section steel members are orthogonally stacked to form a Dougong shape, the wavy-wall cylindrical elastoplastic buffers are arranged between adjacent layers of the section steel members, and the U-shaped sliding connecting troughs are arranged at upper and lower ends of the wavy-wall cylindrical elastoplastic buffers, which realizes a connection between the wavy-wall cylindrical elastoplastic buffers and a section steel in two orthogonal directions. Under an impact of small energy rockfalls, an elastic deformation of the Dougong joint domain is used to achieve a buffering.

Abstract: A two-stage method for a double-row intelligent layout of a workshop based on multiple constraints. The minimum logistics cost function of the double-row intelligent layout is established as the objective function, and the constraints of the function model are established at the same time, to generate the LP model. The initial population of facilities is generated, and the fitness value of each individual in the initial population is calculated according to the LP model, so that the fitness value is used as the current optimal solution. The individual in the initial population is continuously optimized by using the VNS and PMX technologies, and the value of the objective function and optimal sequence of the optimal solution are updated by using the elite retention strategy.
