| 摘 要： | 750 kV西永输电线路工程中采用了斜平面底板等截面斜柱基础，它受力合理，能节省材料，但由于其立柱斜率、基础顶面与地面的夹角较大，且多使用8根地脚螺栓，因此其质量控制点多，基础的施工质量难于有效控制。针对该基础的特点，分析了基本控制数据的计算方法，提出了质量控制难点及解决办法，总结了现场施工经验，为后续超高压输电线路的施工提供参考方案。

| Abstract: | Xi-Yong 750 kV transmission line project adopts inclined flat-baseplate and equal-section column foundation,whose forces are applied rationally and material can be saved.However,due to its rake ratio of columns,big included angle of foundation top to the ground,and 8 foot anchor bolts,there are many construction quality control points and it is difficult to control foundation quality.According to the previous mentioned features the paper analyzed calculation method to calculate basic control data,gave out d... |
