摘要
紧邻河道或在河中设置的铁塔基础,除像常规铁塔基础一样进行上拔稳定、地基压力等方面的设计计算外,还应当将水流流速、水流冲刷等造成的基础倾覆力纳入基础抗倾覆稳定计算中进行重点校核,以"达维"台风中受洪水冲击倒塌的ZGU4型铁塔为计算实例,探讨受水流冲击、冲刷对铁塔基础抗倾覆稳定的影响及设计计算方法。
Tower foundation in a fiver or near a fiver need not only pulls up stability and calculates foundation pressure but only focu- ses check the calculation on resisting overturning. The ZGU4-type power tower is collapsed by the flood caused by the "Dawei" Ty- phoon is taken as a calculation example in this study. The impact and the calculation method for tower foundation when flow velocity and scour are discussed.
