新型等截面斜柱基础上拔—水平承载力试验研究

Test on Uplift-horizontal Bearing Capacity of New Type Foundation with Inclined Equilateral-section-pillar

等截面斜柱基础在送电线路中作为一种新的基础型式,与一般基础相比具有受力合理、节省材料量、施工工期短等显著优点。通过等截面斜柱板式基础上拔承载力试验,采用接近于送电线路直线塔受压实际工作条件的试验方法,验证了基础上拔承载力设计理论、方法以及设计参数取值的合理性、可靠性。试验结果表明,在设计荷载范围内基础是稳定、安全的。

As a relatively new type of foundation, flexible foundation with equal-sectional inclined column has very good bearing capacity. It can also save materials and reduce construction time. By adopting the test condition that close to the actual working conditions of straight line transmission line towers, the reliability of the design method and design parameters for compression bearing capacity are verified. The results show that the foundation is stable and safe within the design load.
