摘要
砂土地基在地震等动荷载作用下会发生液化,导致地基丧失承载力,使基础产生不均匀沉降,造成杆塔倾斜或倒塔。通过分析液化的形成条件及本身特性,提出了在输电线路杆塔基础设计中全部或部分消除地基液化沉陷和减轻液化影响的措施。
Liquefaction of the sand subsoil foundation would may occur in earthquakes and under other dynamic loads, resulting in loss of foundation bearing capacity and the uneven settlement of the basis, and even causing tilting or even toppling of towers. Through analyzing the conditions of liquefaction formations and their characteristics, this paper proposes effective measures on in reducing the liquidation effect and even totally or partially eliminating the liquefaction settlement in the design of the transmission line tower foundation.
