中文摘要：

在充分论证厦门地区现代区域构造应力场基础上,应用叠加断裂作用原理,分析厦门地区的断裂稳定性.厦门地区的断裂可划分为稳定型、基本稳定型、次稳定型和不稳定型4 种.最后,利用地面调查、物探和勘探等综合技术手段确定断裂带的位置,在厦门地区典型的北东向、北西向断裂中采集断层泥样品.通过对断层泥进行显微刻蚀形貌测年、热释光测年及电子自旋共振测年,表明在现代区域构造应力场作用下这些断裂在第四纪时期有过多次活动.证实叠加断裂作用原理在厦门地区断裂稳定性分析中应用的可行性.

英文摘要：

Based on convincing demonstration of modern regional geological tectonic stress field in Xiamen area, with the application of superimposed fault principle, the fault stability in Xiamen area was analyzed. The fault stabil-ity can be divided into the following four types: stable, basically stable, relatively stable and unstable. Finally, using comprehensive technical means, including ground investigation, geophysical prospecting and exploration to determine the location of fault zones, fault gouge samples were collected from the typical NW-trend and NE-trend faults in Xiamen area, the fault gouge dating results of a variety of rock, including SEM, TL and ESR, showed that these faults had multiple activities during Quaternary under action of the regional tectonic stress field. It is confirmed that the ap-plication of superimposed fault principle in analysis of fault stability in Xiamen area is feasible.
