摘要
在不同地质条件下,输电线路采用不同的基础型式可以做到施工简单、结构安全、节能环保和持续发展。人工掏挖基础在硬塑粘土应用中体现出其很好的优越性,为了进一步分析和研究角钢斜插式斜掏挖和直掏挖基础相同和不同之处,本文分别进行了不同尺寸的斜掏挖和直掏挖基础现场对比试验,从基础水平加抗拔承载力、基础位移变化、基础主筋的受力分布、地基土压力和经济指标等方面进行比较。
Under different geological conditions,transmission lines of different type foundations can be done simple construction, structural safety, energy-saving environmental protection and sustainable development.The excavated foundation in hard plastic clay applications shows the great superiority.In order to further analyze and study the similarities and differences of the inclined and vertical excavated foundation,the field tests of the different sizes excavated foundation were carried out and the results were compared based on foundation level plus uplift capacity displacement,steel stress distribution,foundation earth pressure and economic indicators in this paper.
