8 PRELIMINARY TALKING ABOUT MOUNTAIN AREA RAILWAY CONSTRUCTION IN
GAO Si-bin
Due to the high difficulty in engineering works and big investment of the railway constructionin the mountain area，the demonstrations in different aspects should be put forward during setting up the construction projects. The route selection schemes should be economic and reasonable，and the main technical standards should be selected properly- During the research of the route selection schemes，the strip of land between hills should be determined reasonably，and the geological route selection should be taken into attention. Through carefully design，an economic and reasonable route may be selected so as to fulfill not only the requirements of railway transportation，but also to promote the development of the local economy.

13 EXPLORATION ON DEVELOPING TARGET FOR XI '勝XIAMEN RAILWAY PASSAGE
XU Ding-cheng
According to the specialities of the national economic development and the overall arrangement of its railway networks，the author proposes his consideration on constructing the Xi an-Xiamen railw ay passage. The basic direction of this railw ay passage is introduced，as well as its general situation- It is pointed out that the construction of the Xi an-Xiamen railw ay passage will complete the overall arrangement of railw ay networks in China. This railw ay passage is not only a political and national defence line，but also is a line to help the slum district in the mountain area. The construction of Xi-Xia Railw ay will become an economic developing link between inland and Southeast coastal areas，promote development of industry and agriculture along the railway， come off poor to become rich in mountain areas， provide conditions to develop industry of large and middle cities along the railway，and promote the development of tourism along this railway. The author suggests that the Xi-Xia railw ay passage may be constructed in following three steps，i. e. Ankang-Yichang at first， Pingxiang-Yong 'an secondly，and finally Shimen-Xiangtang. The construction of Xi-Xia Railway makes the structure of railway networks reasonable. The Lanxin-Lo nghai-Xixia railw ay line will become the main artery of communication between the East China and West China for economic development，promote peace and unifying the country with Taiwan Province， and create vigorous influence on economy and trade exchange between the two coast.

55 METHOD OF IMAGES FOR DISCHARGE RATE OF THE EXTRA-LONG TUNNELS WITH SUPERTHICK OVERBURDEN
XU Ze-min，HUANG Run-qiu， YAGN Li-zhong
The thickness of overburden of extra-long tunnels often amounts to hundreds of meters，even goes beyond 1000 m. Here， an extra~long tunnel whose thickness exceeds 500 mis called extra~U)ng tunnel with superthick overburden. Their depth in aquifers is big and the initial discharge mainly comes from elastic yield. Moreover，the permeability of wall rock gets ofter poorer and poorer with depth. In view of the above aspects， the tunnels are formularized as the wells near boundaries， and the calculation model for maximum discharge rate is got by way of method of images. Having been simplified properly， the model tallies basically with part of the existing relative models.
