输电线路微型桩基下压承载力特性的模型试验
Model test on compression bearing capacity behavior of micropile foundation for transmission line
摘要
Abstract
Small⁃sized bored grouting micropile is a new type of pro⁃environment foundation for transmission line. The test models of two single micropiles, and one micropile groups were signed and prepared,and the tests on compression bearing capacity behavior of micropile were carried out, and its load⁃deformation behaviors of single micropile and micropile groups were investigated. Besides, the calculation theory of micropile foundation was discussed,and the calculation values of bearing capacities were compared with these of tests. It could be concluded that,the bearing capacities of single micropiles was a relatively bigger than that of test, and the bearing capacity of micropiles groups had a good agreement with that of test.Based on the above analyses,the cap and pile group effect of micropile groups foundation could increase the bearing capacity.关键词
