In this paper, utilizing the failure modes of transmission towers in the ice disaster in 2008, ice load of conductor and ground wire is analyzed.
结合2008年冰灾铁塔破坏形式,对导地线覆冰荷载进行分析,对新老规定进行技术经济比较,提出了铁塔抗冰设计应注意的问题和建议。
Some conclusions are obtained: there is the linearity relation between swelling ratio and initial water content, the maximum water content which causes expansion of the expansive soil and the semi-log relation between swelling rate and cover pressure.
研究南水北调东线江苏段沿线压实膨胀土的膨胀变形特性,得到了压实膨胀土的无荷膨胀率与初始含水率之间呈线性关系以及压实膨胀土发生膨胀变形的上限含水率,得到压实膨胀土的有荷膨胀率与上覆荷载之间呈半对数关系。
