摘要
Abstract
Root pile foundations of overhead transmission lines are applicable for soft soil ground and covers small area. By finite element, design reasonableness of root pile foundation in soft soil and its ability to bear external load are analyzed. The finite element analysis is respectively conducted on external load of places 1 m, 5 m and 8 m away from the bearing platform, from which the displacement and stress are concluded. It is indicated through comparison and analysis on technical parameters that the design of root pile is reasonable and the pile of dirt within 8m from the bearing platform have great impact on root pile foundation. Therefore , the external load should be taken into consideration during the design. The pile of dirt 8 m away from the bearing platform has little impact on root pile foundation, and therefore some structural measures can be adopted to meet the design requirement.关键词
