本文基于以往人們总是把柔性高椿台岸壁結构——有侧移的彈性支座连續梁結构的計算問题,作为特殊的結构力学問题介,所以现有人們较偏爱的力法介,都因为要给予特殊处理,就根自然地采取了間接介的途徑,显见是走了弯路,不如直接解来得簡便。 因此,这里特提出三种直接介法:图介数介法、数介法(一)和数介法(二),三法实际上都是力法,都是把移构当作普通的由受弯构件和定軸力的杆件組成的混合构架,直接用力法介。三法各有各的特点,有一定的实用意义,可供研究和設計人員参考。
This paper is based on the previous problem that people always use the calculation method of the flexible culverts’ quayside structure, which has a laterally-supported elastic bearing continuous beam structure, as a special structural mechanics problem. Because we need to give special treatment, we naturally adopt an indirect way. It is obvious that we have taken a detour and are not as easy as direct solutions. Therefore, three direct methods are proposed here: Intergraph Intermediation, Number Interpreting (1) and Number Interpreting (2). The three methods are actually force methods, and they are all treated as ordinary ones. A hybrid structure consisting of a member with a bending member and a member with a fixed axial force is introduced directly by a force method. Each of the three methods has its own characteristics and has certain practical significance. It can be used as a reference for researchers and designers.
