【摘要】 近年来,随着我国公路建设事业的迅猛发展,高等级公路已由平原地区向山区、由东部地区向西部地区不断延伸。这对公路工程中路基支挡结构的设计提出了许多亟待解决的关键技术问题。本文在锚定板式挡土墙和悬臂式挡土墙的基础上,提出了一种路基新型支挡构造物—路基悬锚式挡土墙。首先,简单阐述了挡土墙的发展概况、分类、适用条件；课题的来源、研究的目的意义及悬锚式挡土墙的特点；其次,详细介绍了土压力的分类及计算方法,在此基础上提出了悬锚式挡土墙各组成部分的设计方法及结构稳定性分析方法；再次,通过对悬锚式挡土墙的工作原理及受力情况的分析,对悬锚式挡土墙进行了优化设计；最后,论述了悬锚式挡土墙的施工组织、程序、施工工艺、要求及注意事项。悬锚式挡土墙适用于缺乏石料、地基承载力低及对抗震性能要求高的地区,它丰富了公路支挡结构的类型并且对于完善有关规范规程及指导公路支挡工程的建设,具有重要的理论与实际应用价值。更多还原

【Abstract】 Recently, with the rapid development of highway construction, highway constantly spreading form plain to the mountains, east to west.many key technical problems demanding prompt solution in highway engineering design of retaining structures.on the basis of studying the anchor retaining wall and the cantilever retaining wall.This paper presents a new type of retaining structures Subgrade Suspendible Anchor Retaining Wall.Firstly, brief elaborate of the classifications, the applicable conditions, the present development situation of the existing retaining wall; also the source, aims and the significance of this project, the features of the suspendible anchor retaining wall are introduced here.Secondly,detailed introduction of the classifications of soil pressure, and the computing methods of soil pressure.Then introduced the design of different components of suspendible anchor retaining wall and the methods to analyze the structure stability. Once again by the analyzes of the working principle and the bearing force conditions. The optimal design is carried on the suspendible anchor retaining wall. Finally, dwells on the construction organizations, plans, programs, crafts, requirement and attentive affairs depend on the construction of the project.The suspendible anchor retaining wall,can be used in the areas which lack of stone, low of foundation bearing capacity and high seismic performance requirements. The suspendible anchor retaining wall enriches the file structure types of highway and be of great both the oretical and pratical value for perfect relevant srandard procedures and guide the construction of highway retaining engineering.更多还原
