摘要
提出了一种新的输电线路基础型式———掏挖式基础 ,讨论了该基础型式的受力特点 ,并与传统的板式基础和阶梯式基础比较 ,得出 :基于广东省的地质条件 ,掏挖式基础适于广东省大多数输电线路的塔基 ,该基础型式结构合理 ,可减少基础土石方开挖工程量 ,节省钢筋和混凝土的用量 ,降低工程造价。广东省 5 0 0kV蓄增Ⅱ输电线路的部分塔基首次采用了掏挖式基础 ,线路已投运一年多 。
A new type of transmission line foundation, dredged foundation, is described with its stress features analyzed. This type of foundation, as compared with conventional bedplate foundation and benched foundation, is suitable for most of the transmission line towers in Guangdong Province in light of its geological conditions. Being rational in structure, the dredged foundation can reduce the amount of excavation, save steel and concrete and lessen project costs. It was applied to some of the towers of 500 kV Xu Zeng II transmission line of Guangdong, which was put into operation in January 1999 and has been in stable operation thus far.
