边距布置对预埋板锚固性能影响分析

Analysis of the Effect of Edge Distance Arrangement to Anchor-Plate Anchor Performance

预埋板作为支架和设备的生根形式,在电力设计中有着广泛的应用。由于其在理论和实践中存在着发生破坏的可能,因此研究破坏产生的机理、影响因素,在工程设计中避免这些不利因素显得十分必要。文章在建立预埋板受力力学模型的基础上,运用极限应力法求解预埋板的极限承载力,分析了影响极限承载能力的因素。在这些因素中,混凝土边距与实际布置密切相关并且对极限承载力有重要影响。

Anchor plate is widely used in power plant as the root of support and equipment. Because it can be damaged theoretically and practically, it is very important to find the reason and the factor cased these damage, and then try to ovoid these harmful factors in engineering design work. Based on the load set and distribution of effort, ultimate load capacity of the anchor plate is calculated using ultimate tension method, and the factor which has effect to the ultimate load capacity is analyzed, the distance between the edge of anchor plate and concrete wall has a significant influence to ultimate load capacity.
