THE INFLUENCE OF THE REGIONAL LAND SUBSIDENCE ON THE ORBIT TRANSPORTATION ENGINEERING OF BEIJING CITY TO TIANJIN CITY AND THE CURE COUNTER-PLANS FOR IT

The orbit transportation engineering of Beijing to Tianjin city is the first high-speed city-to-city transportation railroad that our country will soon carry out, follow the line through several districts of the regional land subsidence, and bring about important influence on the transportation engineering. The geological environment background, the present condition of the regional land subsidence, its reason and the trend of the development, and its influence on the orbit transportation engineering of Beijing city to Tianjin city are discussed in this paper, and the prevention and cure counter-plans are put forward further.
