垂直荷载作用下的厚壁园管计算,是工程中经常遇到的问题。以往的厚壁园管在各种荷载作用下,理论上均宜按弹性力学平面问题求解,这样计算,工作量比较繁重,故除均匀内(外)水压力作用时按弹性力学方法计算外,由其他荷载作用所引起的内力,一般按建筑力学方法进行计算(即按力法算 The calculation of thick-walled tubes under vertical loads is a problem often encountered in engineering. In the past, thick-walled tubes were theoretically solved according to the elastic-mechanical plane problem under various loads. In this calculation, the workload was heavy. Therefore, in addition to the uniform internal and external water pressure, the calculation was based on the elastic mechanics method. The internal forces caused by other loads are generally calculated according to the method of building mechanics (ie calculated by force method).
