在进行村镇下采煤的实践中发现二三层小楼房比同期建造的、且建筑材料和施工质量相当的平房有更强的抗变形能力。这说明建筑物的宽高比在起作用，同时也发现这一现象与“总变形指标”的计算结果不相一致。 In the practice of mining under villages and towns, it has been found that two- and three-story small buildings have stronger resistance to deformation than the bungalows constructed in the same period and with the same building materials and construction quality. This shows that the aspect ratio of the building is working, and it is also found that this phenomenon is inconsistent with the calculation of the “total deformation index.”
