根据EN 1997-1和EN 1997-2，本文件规定了作为岩土工程勘察服务一部分的抽水试验要求。 本文件适用于对含水层进行的抽水试验，该含水层的渗透性是，根据地面条件和用途，从井中抽水可在数小时或数天内降低测压头。它包括在土壤和岩石中进行的抽水试验。 本文件涉及的试验旨在评估含水层的水动力参数和油井参数，例如: -含水层的渗透性， -泵送的影响半径， -一口井的抽水速率， -抽水期间含水层水位下降的响应， -皮肤效应， -嗯，储存， -抽水后含水层恢复的响应。

This document establishes requirements for pumping tests as part of geotechnical investigation service in accordance with EN 1997-1 and EN 1997-2. This document applies to pumping tests performed on aquifers whose permeability is such that pumping from a well can create a lowering of the piezometric head within hours or days depending on the ground conditions and the purpose. It covers pumping tests carried out in soils and rock. The tests concerned by this document are those intended for evaluating the hydrodynamic parameters of an aquifer and well parameters, such as: — permeability of the aquifer, — radius of influence of pumping, — pumping rate of a well, — response of drawdown in an aquifer during pumping, — skin effect, — well storage, — response of recovery in an aquifer after pumping.
