TEXT B. RAILWAY CIVIL ENGINEERING IN JAPAN
(1) Japan is a long island country extending north to south, with numerous mountains rising over 1,000 m above sea level. Flat lands amount to about 16 per cent of the" total area of the country. No wonder tha,t these are the most populated (населенный) territories. Most of the major cities and large industrial centres are located in these parts of the country.

(2) The J.N.R. (Japanese National Railways) network consists of longitudinal (продольный) trunk lines running' through the cities' areas and industrial regions and secon­dary lines crossing the trunk lines at several points.

(3) Another characteristic feature of the railways in Japan is of a civil engineering nature. That is to say, the topographical conditions of the country necessitate the erection of a great number of civil engineering structures such as bridges and tunnels. Frequent earthquakes (землетрясе­ние) and typhoons must also be taken into consideration. Were bridges, tunnels and buildings of conventional design, they might not withstand the forces of strong winds and earthquakes.

(4) As mentioned above, the railways in Japan have many long tunnels. Japanese engineers, however, suggest that still more tunnels should be built. The fact is that the J.N.R. has built several high-speed trunk lines on which trains travel at top speeds up to 250 kph. This, in turn, necessitates the construction of straight (прямой) lines. For this purpose, a number of new tunnelf had to be built and are to be built in the near future.

(5) As rivers in Japan are generally narrow, railway bridges to span them are relatively short in length, but recently longer railway bridges have been erected. As the result of the development in welding (сварка) technique and the,improvement of steel quality, welded bridge structures are likely to be' increasingly built in the Future.

(6) A considerable experience has also been gained in the erection of prestressed (предварительно напряженный) cpncrete bridges. At the same time, Japanese engineers are trying to reduce the weight of reinforced concrete bridges because heavy weight is considered the biggest drawback of the conventional concrete bridge structures.
