标准范围

本文件规定了在岩土工程监测中通过称重传感器测量力。ISO中给出了地面、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？18674-1.本文件适用于:—？锚杆、系杆、桩、支柱、支柱和钢衬等岩土结构的性能监测；—？检查与观测方法相关的岩土设计和施工调整；—？评估施工期间或施工后的稳定性。本文件不适用于在岩土现场试验后故意向岩土结构施加载荷的装置，如用于锚杆拔出试验或桩载荷试验的校准液压千斤顶。注1？根据参考文献[2]和[3]，本文件满足了通过称重传感器对地面、与地面相互作用的结构和岩土工程进行性能监测的要求，作为岩土工程调查和试验的一部分。注2？ISO 18674-7旨在定义通过应变或位移计测量力。

This document specifies the measurement of forces by means of load cells 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.

This document is applicable to:

—     performance monitoring of geotechnical structures such as anchors, tiebacks, piles, struts, props and steel linings;

—     checking geotechnical designs and adjustment of construction in connection with the observational method;

—     evaluating stability during or after construction.

This document is not applicable to devices where the load is purposely applied to geotechnical structures in the wake of geotechnical field tests such as calibrated hydraulic jacks for pull-out tests of anchors or load tests of piles.

NOTE 1       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 load cells as part of the geotechnical investigation and testing in accordance with References [2] and [3].

NOTE 2       ISO 18674-7 is intended to define the measurement of forces by means of strain or displacement gauges.
