A modified Eulerian method for snowdrifts was proposed by introducing the snow particle capture efficiency. The relationships between the modified method and the previous methods were discussed, the results showed that the previous methods are special cases of the modified method. Based on the modified method, the impacts of the location and the height of the interfering building on the snow distribution on the target building were studied. The location of the interfering building seriously affects the snow distribution on the roof of the target building. Four typical interference modes were found through simulations. Significant interference effects on snow load occur when the interfering building is higher than the target building, and it becomes more powerful with the increase of the height of the interfering building.

通过引入雪粒捕获效率，提出了一种改进的雪堆欧拉方法。讨论了改进方法与以前方法的关系，结果表明，以前的方法是改进方法的特例。基于改进的方法，研究了干扰建筑物的位置和高度对目标建筑物积雪分布的影响。干扰建筑物的位置严重影响目标建筑物屋顶的积雪分布。通过仿真发现了四种典型的干扰模式。当干扰建筑物高于目标建筑物时，对雪荷载的干扰效应显着，并且随着干扰建筑物高度的增加而变得更加强大。
