标准摘要
[中文适用范围]: ISO 22282 的这一部分规定了土壤和岩石地质水力学测试的一般规则和原则,作为根据 EN 1997-1 和 EN 1997-2 的岩土工程勘察服务的一部分。 它定义了与土壤和岩石渗透率测量相关的概念并规定了要求。 地质水文测试的不同目的是获得有关自然或处理状态下的土壤或岩石的渗透性、透射率和存储系数以及含水层的水动力参数的信息。 地质水文测试有多种用途,例如: a) 岩体灌浆的吸收能力和有效性; b) 渗漏和排水评估; c) 地下水降低工作评估; d) 大坝截流的影响; e) 隧道和竖井下沉的影响; f) 检查填料或盖的密封性; g) 评估地下液体和悬浮液的流动; h) 制定补救措施计划。 注 1 ISO 14686 涵盖了供水的地质水力学测试。 注 2 对于大多数类型的地面,现场渗透性测试比实验室中进行的测试产生更可靠的数据,因为测试的材料体积更大,并且地面是进行原位测试,从而包括地体结构产生的影响,但避免与采样相关的干扰。 ISO 22282 的这一部分涉及使用地下水执行测试,但没有明确考虑其他流体和悬浮液。 其他流体和悬浮液的流动可以通过应用不同的粘度以及透射率、渗透系数和固有渗透率之间的关系来考虑。 [外文原描述]: ISO 22282-1:2012 establishes the general rules and principles for geohydraulic testing in soil and rock as part of the geotechnical investigation services in accordance with EN 1997-1 and EN 1997-2. ISO 22282-1:2012 defines concepts and specifies requirements relating to permeability measurement in soil and rock. The different purposes of geohydraulic testing are to obtain information on the permeability of soil or rock in natural or treated states, transmissivity and storage coefficient, and hydrodynamic parameters of aquifers. Geohydraulic testing is used for many purposes, such as: absorption capacity and effectiveness of grouting in rock mass; assessment of seepage and drainage; assessment of groundwater lowering work; effects of cut-offs for dams; effects of tunnels and shaft sinking; checking fill or cover tightness; assessment of the flow of fluids and suspensions in the ground; planning for remedial measures. ISO 22282-1:2012 deals with the execution of tests with groundwater and does not explicitly consider other fluids and suspensions. The flow of other fluids and suspensions can be considered by applying the different viscosities and relations between transmissivity, permeability coefficient and intrinsic permeability.
