為對裝配式貝雷梁進行精細化模擬與分析，基于貝雷銷軸的精細化接觸模擬方法，建立貝雷梁實體有限元模型，驗證線性狀態下數值模擬方法的可行性。通過不同側向支撐間距下的穩定分析，研究結構的受力性能。結果表明：銷軸結構具有極大的安全儲備；線性狀態下貝雷梁的有限元模擬分析結果與試驗值較貼合，表明提出的貝雷梁精細化數值模擬方法是可行的；非線性時貝雷梁的側向支撐間距對結構的失穩模式起決定性作用。

In order to carry out fine simulation and analysis of prefabricated Bailey beam, based on the fine contact simulation method of Bailey pin, a solid finite element model of Bailey beam is established, and the feasibility of numerical simulation method under linear state is verified. Through the stability analysis under different lateral support spacing, the mechanical performance of the structure is researched. The results show that the pin structure has great safety reserve. The results of finite element simulation of Bailey beam in linear state are in good agreement with the experimental data,which indicates that the refined numerical simulation method of Bailey beam is feasible. Considering the nonlinearity, the lateral support spacing of Bailey beam plays a decisive role in the instability mode of the structure.
