| 摘 要： | 本文在求解承压水井水位固体潮的扩散方程时增加了井孔压力的边界条件，使扩散方程更符合实际情况，从而得到在理论上更为完善的起潮力位与水位固体潮之间的关系式。文中讨论了气压作用于承压含水层的水力扩散方程和气压对水位固体潮的影响，导出了相位滞后与含水层参数的解析式，为求解含水层参数建立了基础。根据水位固体潮观测资料和气压观测资料，在给定地球模型的勒夫数的情况下，全面地解决了求定观测井含水层参数的方法，并给出了一个实际算例。

| Abstract: | In this paper,considering well pressure as a boundary condition, the diffusion equations of artesian well water level tide better accorded with the actual situation and a more perfect theoretical relational expression between tide generation force and water level tide are obtained.The water power diffusion equation of artesian aquifer affected by air pressure and the effects of air presure on water level tide are discussed.The relational expression between phase lag and aquifer parameters are derived.Thus the basis for evaluation of aquifer parameters are established.On the basis of observational data of earth tide and air pressure and on condition that Love numbers of earth model are given, the problem of determining aquifer parameters of the well observed is solved in an all-round way.Using observational data of water tide and air pressure of a well in Fanxian county,Henan Province the aquifer parameters are evaluated. At last,taking these parameters into account,the response coefficients and phase lag of serveral wave groups are evaluated. |
