发布时间：2018-08-04 15:58
【摘要】：公路桥梁是重要的一项基础设施,在国民综合运输体系中发挥着重要作用,桥梁地基基础方案会影响整个项目的经济效益、社会效益,对周边的环境也会有较大影响。设计比选出能同时满足安全、可靠、经济、环保等方面要求的较佳基础方案,对降低项目成本,促进地基基础改革,具有重大的意义。本文以芜湖长江公路二桥引桥桩基础设计为背景,对桩基础方案进行了比选和分析。首先介绍了永定圩引桥南段的工程地质条件,阐述了桩基础方案的比选方法,并从桩基础的力学性能、施工技术、造价、工期等几个比选因素考虑,对桩基方案进行了初步分析；然后设计出了六个可行的桩基础方案,对各个方案进行了桩基础力学性能、施工技术、造价、工期等方面的计算和分析,得出各方案在各个比选因素情况下的汇总成果；最后通过分析总结,提出了最佳的桩基础方案。本文为芜湖二桥引桥桩基础工程的设计与施工提供了可靠的理论指导和技术保障,累积了重要的研究经验,具有较显著的经济和社会效益。
[Abstract]:Highway bridge is an important infrastructure, which plays an important role in the national comprehensive transportation system. The bridge foundation scheme will affect the economic benefit, social benefit and surrounding environment of the whole project. It is of great significance to select a better foundation scheme which can meet the requirements of safety, reliability, economy and environmental protection at the same time. It is of great significance to reduce the project cost and promote the foundation reform. Based on the design of the pile-foundation of the second bridge of Wuhu Yangtze River Highway, this paper compares and analyzes the scheme of pile foundation. This paper first introduces the engineering geological conditions of the south section of Yongdingwei approach Bridge, expounds the method of comparing and selecting the pile foundation scheme, and considers several factors, such as the mechanical properties, construction technology, cost, time limit and so on, of the pile foundation. Then, six feasible pile foundation schemes are designed, and the mechanical properties, construction technology, cost and duration of the pile foundation are calculated and analyzed. Finally, through analysis and summary, the best pile foundation scheme is put forward. This paper provides reliable theoretical guidance and technical support for the design and construction of the pile-foundation engineering of Wuhu No.2 Bridge approach Bridge, accumulates important research experience, and has remarkable economic and social benefits.
