港口工程中的基础梁的设计,采用文克尔假定计算梁的内力较为普遍。基于这种假定的计算方法较多,也编制了一些图表。 但由于在流动轮压作用下存在一个最不利荷载位置的布置来求出各断面的最大弯矩值的问题,所以计算工作量仍然很大。 为此,本文为我们提供了一套常截面弹性地基梁在集中力和集中力偶作用下的弯矩感应线图,使计算工作简单,方便。这是一般图表中所没有的,在船坞底板计算中尤为方便。
The design of the basic beam in the harbor engineering is generally prevalent with the assumption of Winkel’s calculation of the internal force of the beam. Based on this assumption more calculation methods, but also prepared some charts. However, due to the existence of one of the most unfavorable load positions under the effect of flow wheel pressure, the calculation of the maximum bending moment value of each section is still very large. For this reason, this paper provides us with a set of bending moment induction line graphs of the beams with normal cross-section under the action of concentrated force and concentrated force, which makes the calculation work simple and convenient. This is not typical in charting and is particularly convenient for dock floor calculations.
