In general, Xinjiang section of the new Eusasian Continental Bridge goes ahead along the oasis belt of northern slope of the Tianshan Mountains with advanced economy and concentrated populattion. The main factor to determine the fate of oasis is water. There are relativdy more rivers in Xinjiang section Of the Eurasia Continental Bridge. But as far as the region is concerned, if we take Ururmqi as the boundary, river runoff of the western section accounts for 90%,the eastern section just occupies 10%, so surface runoff is highly concentrated in the west. In this paper, river water envirotnment and ground water environment are evaluated emphatical . On the whole,the status of water environment of seven rivers being evaluated is gradually improved and ground water quality of main cities along the bridge is good. In the future, carrying out sustainable development strategy and doing well in compositive prevention and cure should be long-term guidelines so as to ensure the normal running of the new Eurasia Continental Bridge and economic development along the continental bridge.展开更多

At present, Lianyungang hasundertaken the task of transport for the totaltransit containers along the new EurasiaContinental Bridge. The countries and regionsthat make use of the Continental Bridge toconduct transport include the USA, SouthKorea, Japan, Kazakhstan and Hongkong.Between 1992 and 1995, a total of 8。展开更多

Various disasters, such as flood, strong wind, sandstorm, and roadbed disasters,have been seriously affecting the railway transportation. The field investigation and analysis on thedata collected since 1959 show that: serious floods often occurred when the rain intensity reached25 mm/h or 30 mm/d; the critical wind speed for turning over a train is between 35 m/s and 67 m/s,and such cases happened in draught places of mountain opening and trunk valley; the angle be-tween wind direction and railway is closely related to the thickness of accumulative sand along thelines; roadbed disasters taking the form of side-slope sliding, roadbed sinking and silt turning uptook place in spring when the temperature rapidly rose to 10-15℃ from zero and precipitationcame forth or when the thickness of snow cover on shade slope reached above 20 cm in winter;the disasters taking place in the 1990s were far stronger than those of the 1980s and the order ofhazard intensity along the Xinjiang Line is Urumqi＞Shihezi＞Kuitun＞Liuyuan＞Shanhan＞Hami.展开更多
