Damsite selection of Yilan Navigation Hydro-junction on Songhuajiang River;

Study on the general layout scheme for reinforcement and extension project of Guoyang junction sluice;

The river reach of Dadingzishan Navigation-power junction engineering is characterized by wide grade II terrace,large distance between the two dikes,thick covering of river bed,and strong movability and permeability of riverbed,and the overall layout is the essence of construction of low-head navigation-power junction on the reach.

This paper introduces the selection and application of the large section roadway junction's supporting technology, and the effect of this construction technique's application.

By simulating the large junction support parameters of Zhangbei Colliery with computer software, the reasonable support parameters were obtained.

Based on the traveling wave theory,a new method for determining the junction parameters of piping systems is presented.

Analysis on the junction of main road and driveway;

Considering characteristics of the flow at Y-shaped open-channel junction,the finite volume method on staggered grids is used in a depth-averaged Reynolds stress model to discrete the control equations and SIMPLE algorithm so as to obtain the depth-velocity fields.
