井水位气压加卸载响应比

THE LOAD/UNLOAD RESPONSE RATIO OF WATER LEVEL TO CHANGE OF AIR PRESURE

摘要:

将加卸载响应比的理论和方法引入到地下水位资料中.根据承压井水位的气压效应,将地球表面大气压的随机变化做为加载和卸载的力源,从理论上论证可以应用大气压变化而引起的井水位变化来计算加卸载响应比,并给出了计算方法.以此方法计算了1995年9月20日山东苍山M_S 5.3地震前后鲁14井、鲁15井水位的气压加卸载响应比,分析了其变化特征.

Abstract:

The theory and method of load/unload response ratio is led into the analysis for data of underground water level. Besed on the air presure effect to water level in confined well, taking the stochastic variety of air presure over the earth's surfase as load/unload force, the load/unload response ratio of water level to change of air presure in water well is proved theoratically to be feasible, and the method is given. Using the method the load/unload response ratios of water level in Lu-14, Lu-15 well, Shandong Prov., before Cangshan Ms 5.3 earthquake in 1995 are calculated, and the characteristics of the response ratio change is analysed.
