| Abstract: | The data of cave strain at Yichang Seismostation before the Ms 5.1 Hubei Badong earthquake were analyzed with conventional numerical method and wavelet transform method.The result shows the start time of excavation near by was consistent with the time when the abnormal appeared.However，the mean square variance of observation values was larger than that caused by excavation as 2 times.Therefore the abnormal related to not only the load fluctuation of excavation,but also to other confounding factors or crustal strain changes. |
| Keywords: | cave strain wavelet transform load model Ms5 1 Badong earthquake crustal strain change |
