Study on the load bearing properties of eccentric assembled foundations of transmission lines

摘要

The assembled foundations of transmission lines can effectively promote the standardization, modularization and mass productions of tower foundations. Meanwhile, they can ensure a higher quality, improve the efficiency and mechanization level of construction, and make innovations in the construction mode of transmission lines. Through modifications and improvements in layout type of scaffolds and connection mode, the eccentric assembled foundation consisting of concrete laths and angle steel scaffolds can make the force bearing on foundation more reasonable, and effectively save the steel consumption. Real-model tensile and compressive tests were conducted on the hard clay along the direction of main member and diagonal member of the tower leg. Test results further confirm the foundation's favorable bearing performance, which provides a support for its engineering applications.
