摘要
本文根据投标线路所经地区的微地形与微地貌的特点,在对各类地基岩土工程特性进行研究的基础上,结合沿线岩土条件与工程问题的归类,采取定性分析与定量评价的方法,将沿线的地基条件予以概化,建立了10类岩质与土质地基概化模型,针对不同的地基模型推荐了适宜的基础方案,为全线塔位地基基础方案的优化与量化提供了设计依据。
Basing on the feature of microrelief and microtopography in areas passed by the overhead transmission line of bid project, the paper investigated the engineering character of foundation soils of sorts, classified the soils condition and engineering problems along the line. The method of qualitative analysis and quantitative assessment was adopted, and subgrade conditions along the line were conceptualized, the paper established ten kinds of conceptive models of rocky and soil subgrade, and recommended feasible foundation scheme for different subgrade models which are design basis on optimization and quantification for transmission line foundations.
