Popis: Abstract In order to protect the precious cultural heritage of the pagoda in the mountainous area from the damage caused by falling rocks, we provide targeted and effective research support and protection strategy basis. ABAQUS finite element analysis software is used to accurately simulate and analyze the response of the pagoda under the impact load of falling rocks. Firstly, the geometric modeling of the tower structure is carried out in a meticulous manner to ensure that the model accurately reflects the real shape and structural characteristics of the tower, and the material properties are assigned to it rigorously and accurately, so as to construct a finite element model that is highly adapted to the actual situation. Subsequently, the impacts of falling rocks on the pagoda under different working conditions, such as different velocities, radii, impact angles and impact heights, are comprehensively and systematically simulated to assess the structural safety and stability of the pagoda from all angles. This paper clearly reveals that the velocity, radius, impact angle and impact height of falling stones are the core key position in the structural safety assessment of the pagoda, and they are the decisive factors affecting the structural safety of the pagoda. These findings not only deepen the scientific knowledge of the response mechanism of the pagoda under the impact of falling rocks, but also provide a solid theoretical foundation and a clear direction for the subsequent development of accurate and efficient protection measures against falling rocks.
