From a long time, the lightning protection is always an important question in the electrical construction engineering design and construction, which scientists in the countries all over the world must consider in.
This paper analyses the thunder and lightning causes of a civil aviation airport, according to the average annual lightning days we calculate the lightning activity intensity in some region, on this foundation, we establish the lightning threat model of the civil automatic charging station, and provide the theory basis for the lightning protection design and the analysis of the lightning threat model of the automatic charging station.
The average annual lightning days of a civil airport as shown in figure 1.
So, the first system of the civil aviation automation of charging station is the biggest transient interference sources, the different progress of the first system of any form which is occurred in transient interference is introduced into secondary system by the coupling way to form the transient interference.
The lightning interference model of a aviation airport automation charging station Conclusion With the unceasing enhancement of the information degree in the civil aviation airport station equipment, the extent of the threat by lightning is more and more big.

Compression Testing of Gypsum-Based Composite Reinforced by Recycled Wires from Automobile Tires TESÁREK Pavel1,a, NOVÁK Lukáš1,b, TOPIČ Jaroslav1,c, PROŠEK Zdeněk1,d, NEŽERKA Václav1,e and LIDMILA Martin1,f 1Czech Technical University in Prague, Faculty of Civil Engineering, Thákurova 7, 166 29 Praha 6, Czech Republic atesarek@fsv.cvut.cz, blukas.novak.4@fsv.cvut.cz, cjaroslav.topic@fsv.cvut.cz, dzdenek.prosek@fsv.cvut.cz, evaclav.nezerka@fsv.cvut.cz, fmartin.lidmila@fsv.cvut.cz Keywords: Recycled tires, reinforced gypsum, wire reinforcement, compressive strength, ductility.
The use of recycled materials is nowadays greatly promoted and exploited in many industries, including construction and civil engineering.
The steel wires from old automobile tires are a perfect example – they can be used as dispersed reinforcement for subsoil stabilization in railway engineering.
For instance the railway construction is one of the branches in civil engineering with a huge potential for the exploitation of the recycled materials or waste, and the current research is seeking for the new ways of recycling and maximization of its efficiency [1,2].

Geotextile has been commonly used in civil and geotechnical engineering applications, and the majority of geotextiles is made of nonwoven fabrics.
Introduction The use of geotextile in civil engineering provides soils with functions of reinforcement, drainage, filtration, separation, and moisture barrier, and on the other hand, it also prolongs the life time of civil engineering, shortens construction time, saves raw materials, decreases the engineering cost, and simplifies maintenance.
Geotextiles used to be made of woven fabrics of synthetic fibers; however, due to the excellent performance and low production cost, nonwoven fabrics have now replaced woven fabrics and have been used in soil, rock, and land surface engineering to be part of artificial structures or systems [1-5].
Therefore, the optimal parameter of needle-punch depth is 0.5 cm, the geotextiles made with such a parameter possess good mechanical properties, and thus are suitable for engineering in soil erosion control, as well as road bases and slope stabilization.
