| 摘 要： | 引入地震断错危险性概念 ,用概率表示发生断错的可能性大小 ,断错危险性涉及到地震危险性和断错发生与分布特点。断错危险性的表达式为 :P =P1×P2 ×P3,式中 ,P表示断错危险性 ;P1表示地震发生的危险性 ;P2 指不同震级条件下地表断错出现的概率 ;P3为断错量值分布概率。以中国和世界地表地震断错资料为基础 ,建立震级 -断错概率指数P2 和断错幅度及其分布概率指数 ,包括幅值及其分布、宽度和覆盖层厚度影响等指数P3,为地表断错危险性量化评估奠定了基础 |
| 关 键 词： | 断裂 地震 地表断错 危险性评价 |

| Abstract: | In this paper we introduce the concept of the risk of surface dislocation. The possibility of surface dislocation caused by earthquake is expressed here by probability. The risk of surface dislocation involves earthquake risk as well as the occurrence and distribution feature of surface dislocation. The risk of surface dislocation caused by earthquake can be expressed as (Jiang Pu et al ., 1998): P=P_1×P_2×P_3 where P is the risk of surface dislocation caused by earthquake, P_1 represents earthquake |
