抽水试验测试技术一般包括地下水的水位、水量和水温的测定。本文仅简介水位和水量两方面。一、国外概况 1.测试方法与仪器的选择为使所选择的测试方法和所研制的仪器符合野外实际工作条件与经济上的合理要求,国外十分注重使用条件和经济指标的调查研究,并着重考虑:测试目的(长观或抽水)、测试条件(水位埋深、孔深孔径、出水量和参数变幅等)、工作要求(精度、测
The pumping test technique generally includes the determination of the groundwater level, water volume, and water temperature. This article only introduces the water level and the amount of water. I. Overview of foreign countries 1. Selection of test methods and instruments In order to make the selected test methods and the developed instruments comply with the practical working conditions in the field and reasonable economic requirements, foreign countries attach great importance to the investigation of the conditions of use and economic indicators, and emphasize Consider: test purpose (long view or pumping), test conditions (water depth, hole depth, water output, parameter variation, etc.), work requirements (accuracy, measurement)
