摘要： Pavements of airport runway and apron are subjected to stern stresses imposed by landing and ground movements of aircraft. The stresses are primarily concentrated in touchdown zone and wheel path areas of the pavement structure. This paper proposes that this area can be designed using geosynthetic layer reinforcement to minimise deflection and deterioration of the structure. The reinforcement can reduce the vertical stresses on the underground fuel pipes in the apron area, if used. The concept of ditch conduit reinforcement is suggested where a geosynthetic layer is used within a soil backfill to redistribute load over a conduit leading to stress redistribution. It is observed that the vertical load is significantly reduced by the arching action of the soil mass overlying the conduit. The load can be reduced further by placing a geosynthetic reinforcement layer within the soil backfill above the conduit. It is suggested that the inclusion of a geosynthetic layer in the granular backfill reduces the vertical load on a ditch conduit and the amount of reduction depends upon the tensile modulus, deflection of the geosynthetic and soil arching action. This leads to believe that a reinforced pavement structure for runway and aerodrome apron area improves the load carrying capacity of the pavement to sustain the operations of heavy transport aircraft, including occasional overloading of the pavement. Hence, this paper explores a possibility of using a geosynthetic layer under the runway pavement to provide reinforcement.

摘要： New airport in Gaza Province gives a boost to Mozambique’s tourism and local development The second year of the global pandemic has forced Mozambique to close around 90percent of its beaches and tourist attractions across the country. Filling managerial positions for tourist establishments located at Praia de Xai-xai Beach in Gaza Province is bringing hope and expectations for the region.

摘要： Ayear has passed since I left Beijing.Did the autumn winds blow away my memories of the city?Has the snow frozen the group photos taken with my friends last year?I am missing you,Beijing.How have you been?Only four hours on a flight would take me to the largest city in my mind.The memories from my first landing in Beijing remain vivid.It was September,and I thought Beijing would already have snow,so I wore a winter coat.But it was sunny and warm.Everyone on the street seemed to think I had just returned from a trip to the Arctic.It was my first trip abroad,so everything was very fresh,but I also felt small and lonely.On the trip from the airport to the school,I only exchanged a few words with the driver.I was closed off not only by inability to speak Chinese,but also due to an introverted personality.It has always been a little difficult for me to communicate with strangers.The trees along the way gently swayed as if they were welcoming my arrival,and the journey seemed long.The scenery outside the car window brought all kinds of emotions to my heart,and I started recalling voices from my family:Why spend four years of your youth away from us?Who will you turn to if you get in trouble?

摘要： It was Sunday yesterday,and I was very excited,because I,together with my father,would travel to Shanghai by plane for the first time.We arrived at the airport very early,but my father told me we must wait for an hour.Time passed very slowly!Finally,it was time for us to get on the plane.When the plane took off,I f elt terrible.After a little while,the uncomfortable feeling was gone.Minutes later,the plane flied higher.Looking out of the window,I could see the buildings,fields and roads becoming smaller and smaller.And finally,I couldn’t see them.Through the window,I could only see the blue sky and white clouds.What a nice picture in the sky!

摘要： Dear Thomas Rane,I’m very glad to hear from you.I am looking forward to your coming on Sunday.Because I have a piano lesson on Sunday,I’m sorry I can’t meet you at the airport.Let me tell you how to get to my house.My house is in the center of the city,near a bookshop.It’s far from the airport,so you have to take No.34 bus and get off at the Bohai Street Stop,and then turn left at the second crossing.

摘要： [Objectives]This study was conducted to investigate insect activity rhythms in airport ground cover areas,and provide guidance for insect control and bird strike prevention.[Methods]The daily rhythm of insects in the northern area of the airport was studied,and their activity rhythms and characteristics under different weather conditions were analyzed.[Results]In rainy days,the insect number in the three sample areas was low.In cloudy days,insect activity was relatively stable,and insect number was consistent in the morning and evening,and maintained in a stable range,while in sunny weather,insect activity was increased,and the number changed greatly with time.For a single tussock plant growth area,the number of insects was at a relatively low level under rainy weather.In fine weather,the peak period of insect activity was between 10:00-11:00 and 14:00-15:00.[Conclusions]This study can provide a reference for the formulation of safe flight departure time.

摘要： As the following of ecomomic globlization, it is difficult for an enterprise to success in such fierce and complicated environment just by itself, strategic alliance has already been an important mean to again strisk then enhance competitive advantage. In this paper, by pointing out the importance of strategic alliance toan airport, analysing the key factors in selecting strategic alliance partner, and AHP was applied in the strategic alliance partner selection. By using AHP, airport can analyze potential partners comprehensively, and toselect the best partner according it's own fact.
