[0002] In recent years, more and more ancient buildings appear in people's field of vision, especially ancient city walls. The ancient city walls generally have a characteristic that the height of the city wall is very high, and some even reach dozens of meters. The ancient city wall is usually built by stone blocks. How to ensure the stability of the city wall and prevent it from overturning is a difficult problem. In the traditional technology for constructing super-high ancient city walls, the foundation of the city wall is generally made large and thick, so that the stability of the super-high ancient city wall can be ensured.
