為對裝配式貝雷梁進(jìn)行精細(xì)化模擬與分析，基于貝雷銷軸的精細(xì)化接觸模擬方法，建立貝雷梁實(shí)體有限元模型，驗(yàn)證線性狀態(tài)下數(shù)值模擬方法的可行性。通過不同側(cè)向支撐間距下的穩(wěn)定分析，研究結(jié)構(gòu)的受力性能。結(jié)果表明：銷軸結(jié)構(gòu)具有極大的安全儲(chǔ)備；線性狀態(tài)下貝雷梁的有限元模擬分析結(jié)果與試驗(yàn)值較貼合，表明提出的貝雷梁精細(xì)化數(shù)值模擬方法是可行的；非線性時(shí)貝雷梁的側(cè)向支撐間距對結(jié)構(gòu)的失穩(wěn)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.
