山西省地下水位异常指标的综合评价

Synthetical Evaluation of Anomaly Index of Groundwater Level Shanxi Province

利用山西地区地下水位观测井1993年以来所积累的震例资料,按照这些震例可采用的经验性异常指标,将该时段内的异常进行了逐一清理,再以每一震例的地震为准,对观测井周围4.0级以上地震进行清理,得到某井某一时段内异常与地震的2个系列。根据相关计算公式对单井的异常指标进行综合评判,得出各观测井的异常与地震相互对应程度的综合指标。

Based on the earthquake example data of underground water level on observation wells in Shanxi province accumulated since 1993, the anomalies during the period of time are combed one by one according to the experienced anomaly index which can be adopted. Then the M〉4 earthquakes around observation wells are combed out according to each example earthquake, and two series of anomaly and earthquakes of some well during some period of time are gained finally. Synthetic judgment to anomaly index of single well is made based on calculation with related formula and the synthetic index of corresponding degree of anomaly of each observation well to earthquake is gained.
