In the tunnel projects construction process of our country, there are many crossing karst areas situations. Advanced detection abnormal geological bodies in is essential to ensure safety construction. This paper takes Guizhou Provonce Expressway Project—Xinjie Tunnel as an example. By studying overall situation Xinjie Tunnel, basic principles Ground Penetrating Radar and explained. The methods ...

The Alp Transit Gotthard is an ambitious railway construction project, which will incorporate the world's longest railway tunnel of 57 km travelling through the Swiss Alps and under the St. Gotthard massif. Future passenger trains will journey at speeds of up to 250 km/h, adding further to the highly successful European high-speed network and bringing a huge reduction in travelling time. The co...

In this project fluid flow over various airplane wings was simulated using lattice gas cellular automata (LGCA)[1]. The aim of this simulation was to study how the drag and lift forces on a wing vary for various wing shapes, wing pitches and wind speed. The results of this study are presented, along with key details of the LGCA implementation that was used to construct the wind tunnel and inter...

Swissmetro is a MAGLEV Project between the main cities of Switzerland, designed for a speed up to 500 [km/h] in two tunnels under partial vacuum. Two propulsion variants are considered: the short stators of the linear homopolar motors are fixed with the tunnel tracks; the stator of the motors is on board of the vehicles. The levitation, the guidance and the transfer of energy are independent. T...

The article presents the artistic-educational-research project Tunnel to Third Power, implemented by two communities related artistic and educational spaces: a group of students Artistic Education at Faculty Education, University Warsaw, who are prepared work as art educators, second group: Academy Fine Arts in Warsaw. methodological basis activities was art-based research. theoretical art-as-p...

Knowledge of the ground condition and its hazards can play an important role in the selection of support and suitable excavation method in underground structures. Water transport tunnel is one of the most important structures with regard to the goal of excavation, special conditions and limitations considered in the design and execution of them. Beheshtabad Water Conveyance Tunnel with 64930 me...

Hydroelectric power plants’ open-type surge tanks may be built in mountains subject to the provision of atmospheric air. Hence, a ventilation tunnel is indispensable. The air flow in the ventilation tunnel is associated with the fluctuation of water-level in the surge tank. There is a great relationship between the wind speed and the safe use and project investment of ventilation tunnels. To ob...

In recent years, the development of information and digitalization is growing very rapidly, especially in state distance learning due to COVID-19 pandemic. addition, this era leads need for 21st-century skills possessed by students be survived amid several disruptions various conventional fields. Assignments based on project-based have been carried out chemistry at Indonesia University Educatio...
