摘要
根据现场真型试验 ,研究了豫西湿陷性黄土地区掏挖式扩底桩铁塔基础在下压力、上拔力同时有水平力反复作用下的变形性能及桩土联合作用规律 ,以此对基础的承载能力和工作性能进行了分析评价 .结果表明 ,在此地区采用所设计的基础是可靠的 。
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.
