| In recent years, with the rapid development of economic construction, the foundation establishment and its scale in our country become larger and larger. In the slide governance of railway, highway and other civil fields, we use beams with pre-stressed anchor more and more. It was proved that this structure has good effect. However, in contrast with the wide application of beams with pre-stressed anchor, its theoretical research is very much lag behind. There are not unanimous awareness about it, and all the common methods of beams with pre-stressed anchor have some limitations and defects, so this condition seriously restrains the development and betterment of the technology, and leads the theory of beams with pre-stressed anchor very weak.Recently, with the fast development of computer technology, we begin to use numerical method to analyze beams with pre-stressed anchor, which gives a new way to the design of the beams. Numerical method can consider beam and soil as a whole, combine the actual condition, simulate the realistic interaction of soil and beams, and provide reasonable basis for the design and construction. To strengthen the research of beams with pre-stressed anchor, the paper uses numerical method to analyze beams with pre-stressed anchor in detail.In this paper, firstly, the basic theory of beams with pre-stressed anchor is introduced, secondly, the design and calculation method for the beams with pre-stressed anchor are summarized, and then the concerned theory and program for differential methods are introduced. According to the interaction principles of the soil... |
