大型厂站模块的陆地运输作为建造过程中的重要环节，其整体结构的完好，决定着现场能否实现顺利投产。基于此，本文针对运输过程中发生的紧急制动等多种工况，利用ANSYS模拟软件中mass单元，建立刚性耦合，实现模块内构件的简化，分析运输过程中形变情况；并将模块重量与加速度进行组合，兼顾结构破坏结果及运输中的损伤积累，获取不同重量下发生不同损伤状态时的概率曲线。结果表明，在紧急制动和加速过弯中加速度分别为a 6 24 m/s和a 6 3 m/s时，模块形变由其重量产生的惯性力主导，且随着加速度增大，上部横梁出现较大形变；运输过程保持匀速（匀加、减速）状态及对称的捆绑约束，可避免加速度变化而产生较大形变；不同工况下，模块损伤概率曲线走势基本相同，且随着重量和加速度的增大，发生损坏的概率逐渐增加，此外，在相同条件下，加速过弯更易致使模块损坏。

The land transportation of large plant-station module is an important link in the construction process.The integrity of its overall structure determines whether the field can be successfully put into operation.Based on this, in this paper, the mass element in ANSYS simulation software is used to establish the rigid coupling for a variety of conditions such as emergency braking in the process of transportation, so as to achieve the simplification of the module internal-member and analyze the deformation in the process of transportation.Furthermore, the module weight and acceleration were combined to give consideration to the results of structural failure and the accumulation of damage in transportation, and the probability curves of different damage states under different module weights were obtained.The results show that when the acceleration of emergency braking and accelerated turning is a 6 24 m/s and a 6 3 m/s, respectively, the module deformation is dominated by the inertia force generated by the module weight, and with the increase of acceleration, the deformation of the upper beam is larger.The transport process maintains uniform speed (uniform acceleration and deceleration) and symmetrical binding constraints, which can avoid large deformation caused by the change of acceleration.Under different conditions, the damage probability curve of module has basically the same trend, and with the increase of module weight and acceleration, the probability of damage gradually increases. In addition, under the same conditions, accelerated turning is more likely to cause the damage of module.
