1977年以来,西安市区陆续发现地裂缝,使裂缝附近建(构)筑物遭到不同程度的变形和破坏,直接影响了市政工程建设。因此,弄清该区地裂缝的成因有其重要的现实意义。 地裂缝的分布特征 目前查明,西安市区主要有6条地裂缝带,即铁炉庙—后村—小寨—吉祥村地裂缝带(下文简称铁炉庙地裂缝带)、辛家庙—重机宿舍地裂缝带(下文简称辛家庙地裂缝带)、南廊门—煤矿设计院—南廊村地裂缝带(下文简称和平门外地裂缝带)、西北大学—团结村
Since 1977, ground fissures have been successively found in the urban area of Xi’an, causing the deformation of building structures near the cracks to varying degrees and directly affecting the construction of municipal works. Therefore, it is of great practical significance to understand the cause of the ground fissures in this area. Distribution characteristics of ground fissures It is currently found that there are 6 main fissure zones in Xi’an City, namely the Tiechu Temple-Houcun-Xiaozhai-Jixiang Village ground fissure zone (hereinafter referred to as Tieshu Temple ground fissure zone), Xin Jia Miao - heavy machine dormitory crack zone (hereinafter referred to as Xinjia Temple ground fissure), South Langmeng - Coal Mine Design Institute - Nangang village fissure zone (hereinafter referred to Hepingping field fissure zone), Northwestern University - Tuanjie Village
