The work presents the impact of mining exploitation on residential buildings located in Bytom - in Silesian Voivodeship, in the south of Poland. This is one of the most interesting mining areas in the country. Exploitation works performed here for several decades still give the opportunity to study in a wide range the negative impact of mining activities on buildings. The research focused mainly on the impact of the variable curvature of the mining area on two multi-family residential buildings with similar construction characteristics, erected at the beginning of the last century in traditional brick technology. These objects similar in terms of construction details differ essentially in that the first one is divided by expansion joints while the second one is built continuously, without expansion joints. Both buildings were monitored geodesically during the passage of the exploitation front under them. The measuring work lasted over two years. Based on the observations carried out, the time-varying, real dependence between the size of building deformations and the surface area in their vicinity was obtained. The obtained results were the source data for numerical analyzes capturing the impact of the deforming mining area on the state of stress in the structure of objects. The main purpose of the analyzes was to illustrate the role of expansion joints in buildings subjected to the influence of curvature of the mining origin.

受矿区曲率影响的传统建筑伸缩缝的作用

该作品展示了采矿开采对位于波兰南部西里西亚省比托姆的住宅建筑的影响。这是该国最有趣的矿区之一。在这里进行了几十年的开采工程仍然提供了广泛研究采矿活动对建筑物的负面影响的机会。研究主要集中在矿区的变曲率对上世纪初采用传统砖砌技术建造的两栋建筑特征相似的多户住宅建筑的影响。这些在构造细节上相似的对象的本质区别在于,第一个是由伸缩缝分隔的,而第二个是连续建造的,没有伸缩缝。这两座建筑物在其下方的开采前沿通过期间都受到了测地线监测。测量工作持续了两年多。根据所进行的观察,获得了建筑物变形大小与其附近表面积之间随时间变化的真实相关性。获得的结果是用于捕捉变形矿区对物体结构应力状态影响的数值分析的源数据。分析的主要目的是说明伸缩缝在受矿区曲率影响的建筑物中的作用。获得了建筑物变形的大小与其附近表面积之间的真正相关性。获得的结果是用于捕捉变形矿区对物体结构应力状态影响的数值分析的源数据。分析的主要目的是说明伸缩缝在受矿区曲率影响的建筑物中的作用。获得了建筑物变形的大小与其附近表面积之间的真正相关性。获得的结果是用于捕捉变形矿区对物体结构应力状态影响的数值分析的源数据。分析的主要目的是说明伸缩缝在受矿区曲率影响的建筑物中的作用。
