| 摘 要： | 斜坡地形原状土基础抗拔稳定计算是输电线路工程设计面临的一个重要研究课题。根据杆塔基础所处的位置不同,山区斜坡地形输电线路基础分为斜坡基础和临坡基础2类。基于平地条件原状土基础抗拔承载力理论,推导出斜坡基础有效抗拔深度及抗拔承载力的计算方法,提出临坡基础抗拔土体破坏模式及其判定准则。研究成果为输电线路斜坡地形原状土基础抗拔承载力计算提供了一种理论方法。

| Abstract: | Calculation of undisturbed foundation uplift resistance in sloped terrain is an important research topic for transmission line engineering design.Depending on different locations,line foundations in sloped mountain areas can be divided into 2 categories,sloped foundations and slope-side foundations.Based on load bearing capability theory of undisturbed foundation in flat ground,computation methods of depth and load bearing capability for uplift resistant for sloped foundations are derived.Break modes of slo... |
