摘要
目前平整场地中输电线路基础上拔稳定计算可采用土重法,但山地输电线路日益增加,基础在斜坡场地中的上拔稳定计算成为亟待解决的一个工程问题。基于平整场地中的土重法计算原理,推导了斜坡场地的输电线路基础上拔稳定计算公式,并通过与平整场地下土重法进行对比分析,提出了评价斜坡基础上拔稳定的斜坡承载力系数,得出了斜坡条件对基础上拔稳定的影响及规律,研究成果可为斜坡输电线路基础上拔稳定分析提供理论依据。
At present soil weight method can be used to calculate foundation uplift stability of transmission lines on flat ground.However the gradual increase of transmission lines in mountain areas makes the calculation of uplift stability for transmission lines built on slopes become an urgent engineering problem.Based on the calculation principle of soil weight method on flat ground,this paper deduces an improved uplift stability calculation formula of transmission lines on slopes.By comparative analysis with the case of flat ground,it proposes the slope uplift stability factor and obtains impact and laws of slope condition on uplift stability.The results can be useful reference for foundation uplift stability analysis of transmission lines built on slopes.
