【Abstract】 Through field prototype test, deformation and pile soil interaction law of artificial drilled belled pile tower foundation in West Henan collapsible loess zone are studied under repetitional action of down load and up load with horizontal load, thus the bearing capacity and work performance of the foundation are analyzed. The result indicates that the foundation adopted in this zone is credible and is able to satisfy the design standard for the power line engineering.更多还原
