摘要:

提出了4种斜坡地形输电线路基础和杆塔结构的配合方案:铁塔等长腿配等高基础、铁塔等长腿配深浅基础、铁塔长短腿配等高基础、全方位铁塔长短腿配高低主柱基础,给出了斜坡地形输电线路基础与杆塔结构强度配合以及连接方式确定的原则,阐述了采用有效抗拔深度量化斜坡地形对基础承载力降低、临坡基础破坏模式的方法。

Abstract:

According to characteristics of tower foundation on sloping groud, four kind of solutions are proposed to match up between the base and the tower structure of transmission line. The four proposals are introduced respectively as, equal tower leg length with equal foundation, equal tower leg length with unequal embedded foundation, unequal tower leg length with equal foundation, and unequal tower leg length with unequal foundation. The match up principles are also given. The effective uplift resistance depth was supposed to reflect the bearing capacity of foundations on sloping ground.
