为建立一种切实可行的测试方法,对塑料大棚结构强度、稳定性进行测试,这是当前生产上亟待解决的问题。本文以实验研究为基础而确立的测试方法,包括测试大棚结构的强度、稳定性、风载对结构拔力以及进行破坏性实验等。本文重点论述了风、雪载荷的模拟、加载原理及强度测试的电测法相位移测试法。作为鉴定手段,此种方法具有实用价值。 In order to establish a practical testing method, the structure strength and stability of plastic greenhouse are tested, which is the urgent problem to be solved in the current production. This paper based on experimental research and established test methods, including testing the strength of the greenhouse structure, stability, wind load on the structure of the force and destructive experiments. This article focuses on the wind and snow load simulation, loading principle and strength test of electrical measurement method of phase displacement test. As a means of identification, this method has practical value.
