To examine the influence of
endurance mileage of electric mucking vehicle on work efficiency and cost in
long-distance tunnel construction, the
endurance mileage, loading capacity, and construction demand of the electric
mucking vehicle are analyzed to constructed a configuration model of the
electric mucking vehicle in the long-distance tunnel,
providing guidance for vehicle configuration and scheduling. Considering the
basic assumptions such as muck loading time, muck unloading time, and average
speed, the constraints such as mucking quantity constraint, vehicle number
constraint, continuity constraint, and driving mileage constraint are
constructed. Based on a case analysis, the configuration requirements of
electric mucking vehicle under different endurance mileage of main tunnel and
parallel guide tunnel are calculated, and the configuration differences caused
by the change of endurance mileage in different seasons are analyzed. The
results show that the endurance mileage of the electric mucking vehicle exhibit
a significant impact on the vehicle configuration and operation efficiency.
Increasing the loading capacity of a vehicle is not the best solution to reduce
the vehicle demand, and many factors such as driving distance and endurance
mileage should be considered comprehensively.
