降雨对陕北地区明长城单体建筑的破坏方式主要有水力侵蚀和重力侵蚀两种。研究表明，随着降雨历时的增加，水力侵蚀和重力侵蚀均表现出不同程度的增大。降雨强度的增加不仅使两种破坏发生的时间提前，还大幅增加了破坏的程度。只有降雨量大于12mm的降雨才能对遗址模型产生水力侵蚀破坏，而且随着降雨量的增加，水力侵蚀破坏越严重；遗址模型D2-2和D2-4在降雨中水力侵蚀破坏最严重。重力侵蚀多发生于降雨一段时间之后，具有突发性，通常降雨量大于25mm的降雨才能对遗址模型产生明显的重力侵蚀破坏；遗址模型D2-1和D1-1在降雨中侵蚀破坏最严重。

The destruction of rainfall to the Ming dynasty Great Wall in Yuyang district is mainly caused by water and gravitational erosion. As our research shows, this erosion will be intensified with by increases in the duration and intensity of rainfall, which will cause earlier and heavier destruction of wall structures. Generally, only rainfalls larger than 12mm or 25mm can cause damage to the sites, the damage sustained increasing as rain prolongs. Gravitational erosion usually occurs suddenly after sustained rainfall, and rainfall larger than 25mm with heavy precipitation will naturally lead to gravitational erosion.
