4 DEVELOPMENT OF RESOURCES IN NORTHWEST CHINA AND SPEED UP CONSTRUCTION OF ITS REGIONAL THROUGH RAILWAY NETWORK TRUNK LINES
SUO Zhan-hong, XIANG Yuan
The Northwest China is rich in natural resources. But due to its inner situation，the communications in Northwest China were inaccessible and its economic development was seriously delay. For example，the GDP value of Gansu and Qinghai Provinces in year 1999 were be the 11-01% and 2. 81% of GDP of the Guangdong Province respectively. For developing the great Northwest China，the construction of different foundation facilities should be enhanced at first， especially for enhancing the construction of the regional through railway network trunk lines. The investment environment should be improved，so as to be advantageous for attracting trading company and collecting investments， and to speed up the developing cause of the great Northwest China.

50 CONSTRUCTION PRACTICE OF CIRCULAR SINGLE-WALL STEEL COFFERDAM FOR SPREAD FOUNDATION UNDER DEEP WATER
WANGAi-guo
The total length of Guixi Xinjiang extra-long railw ay bridge is 798. 34 m. The width of water river is about 400 m， and the depth of water is 7. 0 to 11. 0 m. The bared bed-rock is distributed with gullying s. There are 11 piers in water， which are partly designed for spread foundation (7-piers) at deep position. The foundation bases locate 5 to 6 m beneath the bedrock. After fully compared，we selected the circular single-wall steel cofferdam and the ling tremie concrete seal at the bedrock. This construction practice is very special. The paper describes all the key working procedures， including the choice of construction practice， the design， machining，welding， assembling and sinking of the cofferdam，and also the ring tremie concrete seal at the foot corner of cofferdam and bedrock. Finally， the paper tells several key points that must be noticed in the construction procedure.

54 STUDY ON BASE ISOLATION ON THE SEISMIC RESPONSE OF SIMPLY-SUPPORTED BEAM BRIDGE
ZHANG Jun，YAN Gui-ping
In this paper，a nonlinear model for time-step analysis of simply-supported beam bridges subjected to earthquake motions was developed. The focus of the study was on elastomeiic isolations with lead cores. The hysteretic behavior of isolators and the column was taken into account by tiilinear and bilinear model respectively. The nonlinear analysis showed that，contrary to linear theory prediction，the use of isolators does not necessarily increase the displacement of the superstructure. Furthermore，it was showed that properly designed isolators could reduce both the ductility demand and internal force in RC bridge columns substantially.

86 VALLEY MORPHOLOGY AND VALLEY SIDE STABILITY OF LIZIGOU RIVER IN NEIJIANG-KUNMING RAILWAY
JIANG Zhong-xin，ZHANG Jun
The Lizigou long bridge is a dominant engineering of the Neijiang-Kunming railway， and the stability of high and steep slope of No. 11 pier in the bridge is a misgiving problem. With the observation and analysis to the morphostructure，the river valley shape and the correlative sediments of Lizigou area， it is considered that the step-spur on the back of No. 11 pier slope is a high terrace of Lizigou river，which is not a unfavorable geological accumulation form and is stable as a whole-During digging slope of the No-11 pier， the influence of engineeing activity is only on surface， and the whole stability of the slope is not shaken. Therefore， the design plan of reinforcing the slope is feasible.
