| 摘 要： | 结合龙门山断裂带其他跨断层资料，对耿达短水准在汶川8.0级地震前后的观测资料进行了重新分析，发现耿达短水准在汶川地震前后的异常为当地居民修建生活小区所致，不应视为地震前兆异常。

| Abstract: | Combining the other data cross Longmenshan fault,we have made a frech analysis of the short-line leveling at Gengda before and after the Wenchuan earthquake.It is found that the change of the short-line leveling was caused by construction of living houses in the locality,but earthquake pracursory anomaly. |
