井字梁的内力计算繁琐而复杂.本文介绍的计算方法是根据小型水电站中水轮机层底板井字梁的结构形式及荷载特点,在计算中抓住其中最主要、最关键的东西,而摒弃那些对计算结果影响甚小,却造成计算过程十分复杂的因素.此法曾在汉中市留马山水电站等工程中实际应用,效果良好.本文即通过实例,着重介绍简化计算的方法和步骤。 Computation of internal forces of tic-tacbeons is cumbersome and complex.This paper describes the calculation method is based on the structure and load characteristics of the wellbore beam at the turbine bed in small-scale hydropower station, to seize the most important and most critical things in the calculation, Has little effect on the calculation results, but causes the calculation process is very complicated .This method has practical application in Hanzhong stay Mashan Hydropower Station and other projects, the effect is good.This article through examples, focuses on the introduction to simplify the calculation methods and steps.
