摘要
我国地域广阔,气候跨区域变化较大,地形地貌复杂多变,各地区风、雨以及导线覆冰的分布规律千差万别。由于目前环境荷载因素对输电塔线结构的严重破坏频繁发生,造成了巨大的经济损失。因此,有必要建立输电塔线结构环境荷载响应分析理论和进行设计优化,提高其结构设计的规范水准,并加强灾害监测控制。这对减轻环境荷载造成的输电塔线结构的灾害具有不可估量的作用。
Due to the vast terrain of our nation, there are dramatic climate changes among regions as well as complex and various terrains. There are huge differences in the distribution of wind, rain and conductor icing among regions. Hugh economic losses are caused by frequently occurred environmental load induced tower structure damages. Therefore, it is necessary to establish analysis theory of transmission tower response to environmental loads and perform design optimization to improve the level of design standardization and strengthen disaster monitoring and control. It plays an immeasurable role in alleviating tower structural damage caused by environmental loads.
