Study on the Cool Flow Field in Trapped Vortex Combustor with Air Injection
As one new type of Combustor with the character of high efficiency,low pollution, and low lean burnout（LBO）,the trapped vortex combustor（TVC） has made numerous scholars pay much attention on it all over the world.It appears in 90s of 20th century, and now has been developed into the High Pressure TVC as the fourth generation.In order to [...]
The Research on Numerical Simulation of Flow Field for Regulation Engineering in Wuqiao Waterway
Wuqiao Waterway runs through Wuhan City,Which lies in the middle reach of the Changjiang River,begins,at Yangsimiao in Hanyang and ends at Wuhan Changjiang River Bridge,and it is a narrow straight waterway whose overall length is 5km.There is Baishazhou Waterway in the upper reach and Hankou Waterway in the lower reach.There are Baishazhou Shoal,Qianzhou Shoal,Huangwuli Side [...]
Analysis of Stress Characteristics of Pressure Dispersion-Type Anchorage Cable and Reinforcement Effect for Slope
In order to meet the requirements of China’s economic development, a lot of high-grade highways and energy bases are established, the deep cut-covering is inescapable, and so it is very important and necessary to ensure the stability and safety of high-steep slope. The prestressed anchorage technique is an advanced technology in the reinforcing slope field, [...]
Study on Performance-Based Fire Protection Design Applicated in
Urban Traffic Link Tunnel (UTLT) is a novel type underground transportation system. It consists of main tunnel with loop shape and several linked tunnels, and always locates in the important and prosperous district. Compared with common road tunnel, UTLT has more complicated design of structure, ventilation and smoke evacuation systems, greater grade of link tunnels, [...]
Research on the Platform Screen Door Impact on Subway Station Environment
Subway system mainly built under the ground is a mass of urban rail transitsystem. With the population and economy developed rapidly, expansion and traffic arebecoming increasingly prominent problem in recently years. Beijing, Shanghai, HongKong, Shenzhen, Guangzhou, Tianjin and other cities have a rapid development insubway. Beijing is the political, cultural and international exchange center that [...]
Experimental Research on Cement Injection Pile Composite Foundation and Numerical Simulation Analysis
In 1991, the Ministry of Communications functioned as the planning of the national arterial highway made a plan which called five verticals and seven horizontals. In 1991, the highway was only several hundred kilometers, and up to last year there are already 50,000 kilometers. Every year there are several hundred billion used in the expressway [...]

The Numerical Simulation Analysis of Replacing Concrete during Construction in Slotted Dam
With the time going on,the concrete dams grow aging and then there are many problems of the dam such as falling intensity of the concrete,seeping,cracking,the lower security and durability.So the systemic study on reinforcement of the old dams is popular in the worldwide field of hydraulic structure all along.At present,a new technique,forming inner wall to [...]
Study on Electrical Load Shift Rate of Variable Mass Energy Storage Air-conditioning System with Partial Storage Strategy
Variable mass energy storage air-conditioning system is also called variable mass energy transformation and storage system,abbreviated VMETS.It uses a new potential storage technique.During the system operation,the mass and concentration in working fluid storage tank is variable,and as a result,the chemical potential is changing,which leads to achieve energy transformation,storage and release.This paper gives a simulating example [...]
Numerical Analysis on Stability of High Rock Slope and Mass Parameter Back Analysis
Rockfall, landslide and mudflow caused by slope stability failure which is a common problem in the range of engineering field such as mining engineering, civil engineering, railway and highway engineering, hydrological and hydroelectric engineering, waste residue and garbage management engineering, together with earthquake and volcano eruption are considered to be the most disastrous geological hazard [...]
