大同市地裂缝场地破坏强度分带与建筑物安全距离的确定

ZONATION OF DAMAGE STRENGTH AND DETERMINATION OF SAFE DISTANCE OF BUILDINGS AT GEOFRACTURE SITE IN DATONG CITY

大同市地裂缝已经给该市造成了严重灾害，由于地裂缝具有构造性质，因此对建筑物的破坏具有不可抗拒性，如何有效地利用宝贵的土地资源，又能防止和减轻地裂缝灾害，最有效的方法是采取避让一定的距离，即所谓的安全距离，本文根据多年来在大同市地裂缝研究中的实际资料，探讨使用综合方法对地裂缝场地破坏强度分带与建筑物安全距离确定，为大同市地裂缝场地的合理使用提供科学依据。

Geofractures have brought about serious hazard in Datong City. Because the geofractures have tectonic characters, it is resistless to damage buildings. How the precious soil resources are utilized? The most effective method is to adopt keeping a certain distance, i.g. safe distance. Based on the actual information of investigation on geofractures in Datong city over several years, the zonation of damage strength and determination of safe distance of buildings at geofracture site were studied using the synthetic method. Thus provide scientific basis for a reasonable use of geofracture site in Datong city.
