| 摘 要： | 榆林地区属于陕北黄土丘陵和毛乌素沙漠接壤地带,送电线路走廊周围地形平坦,地下水较为丰富。针对基础施工中出现“流沙现象”和不均匀地层等不良地质情况,经分析认为,本地区送电线路铁塔基础设计及施工不宜采用普通的大板武或台阶式现浇钢筋混凝土基础,采用复合沉井基础能很好地解决基础不均匀沉降和施工困难等问题。

| Abstract: | Yulin region is situated in the zone of juncture of Mu Us Desert and loess hill-gully area,transmission line corridors are flat and affluent in groundwater. The worse geological phenomena occur during foundation construction,such as "shifting sand", inhomogeneous stratum, etc. In this area, design and construction of rigid or bench cast-in-place reinforced concrete foundation for power transmission tower shouldn't be considered due to unequal settlement and construction difficulties,while it is suggested to adopt composite sunk well foundation in Yulin region. |
