典型微地形下高压输电线路风振响应

Gaoya dianqi
针对现有研究及相关规范中对微地形风场特性考虑不足的问题，文中首先选取了垭口型和高山分水岭型两种典型微地形区域，在考虑地形参数的前提下对其风场分布进行了仿真分析；其次以数学公式的形式建立了风速数据和地形参数之间的关系；最后选取了实际工程中的输电线路为计算案例，进行了风振响应分析，总结了不同微地形对响应数据的影响。文中的研究为经过复杂地形的输电线路设计及运维提供了一些理论依据和研究思路。

土地利用/土地覆被镶嵌体的分形结构模型研究

Shuitu Baochi Xuebao, 2004
运用分形理论对四川省汶川县土地利用/土地覆被镶嵌体景观类型的分维值进行计算,并讨论了各种景观类型的分维性质。结果表明:土地利用/土地覆被镶嵌体具有统计意义上的自相似性,是一种随机分形结构;景观类型的分维值越大,其形态越复杂,反之越简单。SI(稳定性指数)>0,表示景观在其形态复杂状态下的一种稳定性,SI越大,该景观形态越稳定;反之亦然。SI<0,表示景观在其形态简单状态下的一种稳定性,SI越小,该景观形态越稳定;反之亦然。景观类型的分维值随时间变化而增大,该景观的形态变得复杂,反之 ...
