标准范围

ISO 18674-2:2016规定了通过岩土监测用伸长计测量沿线位移的方法。ISO 18674-1中介绍了地面、与地面相互作用的结构、岩土填料和岩土工程性能监测的一般规则。如果与ISO 18674-3结合使用，本文件允许测定任何方向的位移。ISO 18674-2:2016适用于:-监测土壤、填料和岩石的行为；-检查与观测设计程序相关的岩土工程设计；-推导岩土工程关键参数（例如，根据桩荷载试验或试挖隧道的结果）；-在施工前、施工中或施工后评估稳定性（例如，天然边坡、边坡开挖、路堤、开挖墙、基础、大坝、垃圾场、隧道的稳定性）。注:根据参考文献[5]和[6]，本文件满足通过引伸计对地面、与地面相互作用的结构和岩土工程进行性能监测的要求，作为岩土工程勘察和试验的一部分。

ISO 18674-2:2016 specifies the measurement of displacements along a line by means of extensometers carried out for geotechnical monitoring. General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674？1.If applied in conjunction with ISO 18674？3, this document allows the determination of displacements acting in any direction.ISO 18674-2:2016 is applicable to:- monitoring the behaviour of soils, fills and rocks;- checking geotechnical designs in connection with the Observational Design procedure;- deriving geotechnical key parameters (e.g. from results of pile load tests or trial tunnelling);- evaluating stability ahead of, during or after construction (e.g. stability of natural slopes, slope cuts, embankments, excavation walls, foundations, dams, refuse dumps, tunnels).NOTE This document fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of extensometers as part of the geotechnical investigation and testing in accordance with References [5] and [6].
