| 摘 要： | １９９５年２月茄子山水库区发生了４．１级和４．２级地震。地震特点表明与水库蓄水有关。本分析了茄子山水库区的地质构造、构造应力状态、渗漏条件、地热和其它诱发地震条件，判断了茄子山水库诱发地震可能性，利用综合影响系数公式讨论了茄子山水库诱发地震的最大震级。

| Abstract: | The anomalous variation characteristics and mechanism at level marks in Shandong before the Cangshan earthquake of M 5 2 are analysed in this paper.The authors think stress accumulation and regulation process of large scope occurred before the Cangshan earthquake;long-medium-short term deformation anomalies appeared at Gaoya and Fengjiafangzi level marks with the anomalous time of 11 months, the amplitude of 1 68m and the anomalous time of 2 mounths,the amplitude of 0 58mm, respectively,and the earthquake occurred in the turning and recovering process of the anomaly. |
