1 ENHANCE THE CONSTRUCTION OF EASTWARD RAILAY PASSAGES FOR CHUAN-YU RAILWAY
CHEN Ying-xian
The suggestion has been proposed for constructing the Rong Yu-Hu Railway with total length near1y 2200 km for Rong-Hu Railway and nearly 2100km for Yu-Hu Railway. This railway passage consists of the existing railway，the railways in course of construction and the newly-built railways. Besides the railways in course of construction，it is necessary to construct newly-built railways nearly 720 km，increase No. I line for existing railways nearly 450 km and enlarge capacity for single-line railways nearlys 430 km. The whole passage passes through Sichuan，Chongqing，Hubei，Jiangxi，Anhui，Jiangsu to arrive at Shanghai，connecting five provinces and two municipalities directly under the Central Government with three provincial capitals and thirteen regional cities. Therefore，the traffic conditions of the railway networks arc improved，such as the travelling distance between Wuhan and Shanghai may be decreased more than 200 km，the traffic load of busy sections in trunk lines of networks may be reduced，so as to make the trunk lines unimpeded and the traffic flow more reasonable.

4 EXPLORATION ON SEVERAL PROBLEMS CONCERNED WITH RAISING SPEED ON EXISTING RAILWAY LINES
CHEN Hong-nian
Raising speed on existing railway lines to meet the needs of railways facing on the market has become a common programme. During the survey and design for raising speed on existing railway lines，the conceptions of "up to speed" and "raising speed" should be taken into attention to distinguish. The final targets of them are to increase the travelling speed and to reduce the travelling time. In order to increase the travelling speed，the comprehensive measures should be adopted and the treatment of follwing relations should be taken into attention，such as the relation between investment and benefit of engineering project，between short-term installation and long-term planning between reconstruction of civil engineering and renewal of portable equipment，between raising speed of passenger trains and freight trains，etc.

113 SEVERAL THINKINGS CONCERNED WITH RAISING MANAGEMENT LEVEL FOR OPERATION OF CONSTRUCTION WORKS
LIU HUI
The China Railway Engineering Corporation and its stock-controlled group companies arc the enterprises whose main operations arc the overall contracting of projects. Science-technology innovations and technical improvements arc the motive power for enterprises to enhance the competition ability in market. The spirit of the enterprises is based on personnel and for the strengthening of management. It is necessary for sustained development of the enterprises by applying the "four new" technologies to raise benefits of enterprises. Therefore，we should:(1)establish fully quite new cost idea in operation of products and raise the technical contents in the economic benefits，(2)enlarge the working extent to promote technical and management innovations，(3)put "let client satisfactory" as the largest target of the enterprises，(4)establish the famous brand idea and strengthen the superiority of professional construction，(5)develop the recommendation，training and technical support for technical talents through multi-means，(6)advance the thinking about construction and extra- advance making the technical reserves in good order，(7)put forward the "three unification"，leading by typical examples to raise the overall construction management level and the construction quality，(8)based on personnel，pay attention to the methods for making management works in good order. These transformations in eight aspects are very necessary for the long-term development of the enterprises.
