Excavation method for deep foundation pit and top - down construction technique of ribbed plate anchored retaining wall 深基坑开挖与板肋式锚杆挡墙逆作法施工技术
The pre - stressed anchor supporting structure with beam and column is analyzed theoretical in this paper , combined with theoretical study and design of such supporting structure , which is one of the plan projects of construction science and technology in hunan province . the topic provides engineering aiming with practical and concise computation method , and also provides the advice for structure with proper theory foundation and schemes to some extent 本文结合湖南省建设科技计划项目“永久性肋梁柱锚杆挡土墙设计关键问题及计算软件开发” ,对预应力肋梁柱锚杆支挡结构进行了理论分析,提供了适合于工程的、比较简捷的实用计算方法,同时也为该类支挡结构设计提供一定的理论依据和设计建议。
Application of the new type wall in engineering practice proves the feasibility and advantages . in the end , comparison between measured data from quite a few engineering examples and calculated theoretical results shows that , the design methods of anchored bar retaining walls and block retaining walls presented in this paper are reliable , which also have a better bearing behavior and good social and economic benefits 最后通过计算实例以及现场实测结果的对比分析,证明了锚杆挡土墙和砌块式挡土墙的设计计算方法是安全可靠的,同时证明了锚杆挡土墙和砌块式挡土墙优越的受力性能以及其良好的社会经济效益。
Consequently , to optimize the appearance and structure design of retaining walls , especially to have a deeper understanding of the bearing mechanism of various retaining walls and select city retaining wall type reasonably are of great engineering significances and potential economic effect . based on a thorough analysis of the character and mechanism of city - retaining - wall structures , the design theories , construction technology , new wall types and development tendency are deeply discussed . besides , the characteristics of various types of city retaining wall are discussed , and the usual methods for earth pressure calculation are summarized 本文在综合分析目前常用城市挡土结构的特点及其受力特性等基础上,针对一般挡土墙设计理论、施工技术、新型结构以及未来的发展趋势进行了深入探讨,论述了城市挡土结构的特点,并对常用土压力理论进行了综述,介绍了城市挡土墙常见的类型,并介绍了常规的设计理论和方法;通过分析比较,优选出锚杆挡土结构和砌块式挡土结构,并从锚杆锚固原理出发,结合工程实践和大量现场试验、对锚杆的抗拔承载力进行了深入研究,提出了用调整双曲线模型法计算锚杆抗拔承载力的方法,对土压力计算方法进行了探讨,对其设计计算方法进行了研究。
