工业区位论In recent years, with the construction of national infrastructure and increase investment in increasing people's living standards, a wide variety of engineering structures appear like mushrooms, and various types of work based on the foundation of buildings and structures, and its stability and security of the whole project a direct impact on the quality of good or bad. Pile foundation - the basis of this important type of high-rise buildings and all kinds of high-level bridges, river-crossing, sea-crossing now has been made more and more widely. How to choose a reasonable pile construction and control, determining the quality of the project, construction progress and construction, an important factor in economic benefits. Therefore, many workers in the choice of the design of pile-type must be carried out when site visits and research, a comprehensive analysis of various factors in the selection of the most reasonable based on the type and parameters of the pile, with a view to achieve the desired effect of the construction. Industry are aware, the bored piles and prestressed high-strength pipe PHC which is now all types of bridge construction projects in particular, marine engineering (offshore platforms, etc.) than the lower part of the structure of a widely 曹限东
used type of foundation, but in the structure of two types of pile foundation, construction technology, capacity, construction impact, productivity, cost-effective and so there is a big difference, and the scope of application of different terms and conditions, how to choose has become the pre-construction, we must consider. This paper on the new Shanghai A15 highway viaduct lower part of the main line of new construction of two types of pile foundation pile foundation of the comparative analysis, including: foundation structure, construction method, the bearing capacity, productivity, environmental impact, respectively, pointed out that this two pile and the pros and cons of the application, design and construction of pile foundation for the guidance of comments and suggestions.
