FIELD MEASUREMENT OF CONTACT NETWORK PILE FOUNDATION FOR AN ELECTRIC RAILWAY TRACK IN A DESERT REGION

The earth pressures and displacements of four types of pile foundation are measured in situ in Zhongwei-Gantang section of Baotou-Lanzhou electrified railway. Three kinds of pile foundation, i.e. H170, H60 and G200/13, are pointed out to meet the requirements of stability based on the measurements. Methods for economising on concrete masonry and improving the stability of foundation are presented in this paper.
