各种风载和各种立根承载率同时作用时,如何确定许用轻放井架大钩载荷长期来是一个难题。原因在于这是一个相当复杂的问题,并且主要法规中没有规定如何确定这种大钩载荷。但是给出轻便井架设计规范这种方式就包含了如何确定大钩载荷。本文给出了因风 When all kinds of wind loads and various vertical bearing capacity are applied at the same time, it is a long-term problem how to determine the allowable load of the derrick hook. The reason is that this is a fairly complicated issue and there is no rule in the main statute that defines how to determine such a hook load. However, given the design specification for the light derrick, this method includes how to determine the hook load. This article gives the wind
