输电线路斜置角锥装配式基础承载性能试验研究
Experimental Study on the Load Bearing Capability of Oblique Pyramid Eccentric Assembled Foundation in Transmission Line
摘要
Abstract
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 improve foundation force bearing and effectively save steel consumption.Real-model tensile and compressive tests are conducted on the backfill clay along direction of main member and diagonal member of tower leg.Through analysis of load displacement curves,steel bracket stress strain relationship,surface cracks and base soil pressure distribution law,mechanical performance and fault status are tested and verified.The ultimate tensile bearing capacity of the eccentric assembled foundation is 1.5 times that of the design value,and the ultimate compressive bearing capacity is 1.8 times.The basic structure is still in elastic state and can meet design requirements under those conditions.The results can provide reference for future engineering applications in transmission line.关键词
