摘要
对一个满足Theis假设的承压含水层进行抽水试验后,依据Theis模型中s与t之间的比例关系(降深比值法),构造出新的函数W0(u),在此基础上提出采用优选逼近方法求解水文地质参数的原理,并利用C#.net编写了基于WindowsCEforpocketPC2003的应用程序,构成一个可在野外现场试验中移动使用的嵌入式系统。一方面,计算机程序的使用降低了误差,简化了求解过程;另一方面,可利用算法优势和pocketPC的无线移动通信功能为抽水试验现场提供决策支持,有利于及时反馈计算结果,为抽水试验提供有效参考。
After pumping test is put up on the confined aquifer, which meets the Theis′s equation,a new function is constructer based on some certain ratio of observation time to the drawdown of groundwater head in Theis′s model,which the ratio is so called the drawdown ratio.Then,the optimized approximate algorithm is adopted to Theis′s equation calculation in this article. In order to be more available in the field pumping test, the program is written by C#.net based on the Windows CE for pocket PC 2003. This embedded system can be used in a mobile situation and provides the capability of wireless communication. In general, the optimized approximate algorithm simplifies the solving process and lightens the workloads. Moreover, the advantage of this algorithm and the mobile communication function provided by the pocket PC can be available for decision support in the field pumping test.
