蕪湖長江公路二橋引橋樁基礎(chǔ)方案設(shè)計與比選研究
[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.
