By optimizing the pattern of water conveyance,the flow regime in the chamber has been ameliorated,and the safety of the navigation has thus been guaranteed.

This paper analyzes the selection of long-distance water-supply methods in hydraulic engineering, expounds the principles that should be followed in water-supply main trunk, and selects three kinds of water transmission schemes.

Choice of transportation modes for green ore in gold mine;

Symbiotic model of urban transportation mode base on Logistic equation and its evolution mechanism

Research on optimization of transportation mode and route for hazardous materials transportation network

The paper quantitatively discusses the attractive- ness of highway to the potential transport modes and its interfer- ence effects,establishes a tramport passage sharing model using the thought of SUE(Stochastic User Equilibrium)and finally de- picts on the influence mechanism of highway in the other tram- port modes.

Through analyzing the ecological and economic indexes of transport system, the essay compares the influence of each transport mode on many aspects, such as land occupancy, energy consumption, passenger and freight turnover, pollution, environmental effect, safety and convenience.

Furthermore,the performance of each transport mode can not be simply expressed as good or bad.
