采空区建筑物的变形特性研究，一直是采空塌陷灾害的一个重要方向。本文以北京市房山区史家营乡大村涧村采空塌陷为背景，在充分分析采空区上方建筑物砖墙上裂缝形态及分布规律的基础上，从建筑物受力方面探讨了裂缝产生的原因，并采用数值模拟方法对采矿影响下建筑物的变形破坏机理进行浅析，研究结果不仅可为建筑物加固和维修提供依据，还可为采空塌陷区治理提供参考。
採空區建築物的變形特性研究，一直是採空塌陷災害的一箇重要方嚮。本文以北京市房山區史傢營鄉大村澗村採空塌陷為揹景，在充分分析採空區上方建築物磚牆上裂縫形態及分佈規律的基礎上，從建築物受力方麵探討瞭裂縫產生的原因，併採用數值模擬方法對採礦影響下建築物的變形破壞機理進行淺析，研究結果不僅可為建築物加固和維脩提供依據，還可為採空塌陷區治理提供參攷。

Deformation analysis of the buildings on the surface of mining collapse areas is an important theme to study collapse calamity. Based on the building deformation characteristics of Dacunjian, the shape and the distribution of the cracks developed on the walls were fully analyzed, and the reasons leading to the cracks were discussed. Then three-dimensioned numerical model was used to simulate the deformation process due to mining. The results can not only offer the basis for building maintenance and reinforcement, but also give reference for the regulating of mining collapse area.
