摘要
根据该区地裂缝大量调查测试资料，从区域地质背景、土体工程地质性质、水文地质条件及地裂缝动态监测等方面，借助地理信息系统（ＧＩＳ）技术和数学统计方法，研究了地质构造、土体类型、厚度、地形坡度、基岩面起伏及建筑物结构类型等因素与地裂缝灾害的关系，结合地裂缝形态和动态变化特征，认为该地裂缝灾害是由于该区中更新统土体的膨胀性所致。
This paper gives a definite answer based on an integrated researches with geological condition analysis, GIS and the statistic method Many possible influencing aspects about the buildings crazed are studied, such as the characteristics of cracking hazard points distributing in space and variation trends in time, the relationships between cracking hazard points and local geological structure, soiltypes and depths, surface and base slope degzees, the constwction or building types etc A lot of experiments for soil physical and soil mechanics and some special expansion indices are also tested, and the variations trends of cracks in buildings are studied comparatively with the variations of local groundwater level On the basis of all the research results, it is considered that the constructions crazed in Chongyang are caused by the expansibility of Q 2 soils, which are as the main constructions bases
