标准范围

本文件涉及用于测量峰值和重塑叶片抗剪强度以及细粒土敏感性的现场叶片试验的设备要求、执行和报告。此外，还可以评估峰值后的抗剪强度行为。介绍了两种现场叶片试验:普通现场叶片试验（FVT）和快速现场叶片试验（FVT-F）。附录D中描述了叶片试验结果的不确定性。注1:根据EN 1997-1和EN 1997-2，本文件满足作为岩土工程勘察和试验一部分的现场叶片试验要求。注2:本文件涵盖陆上和近岸现场叶片测试。

This document deals with the equipment requirements, execution and reporting of field vane tests for the measurement of peak and remoulded vane shear strength together with the sensitivity of fine-grained soils. In addition, post-peak shear strength behaviour can be evaluated. Two types of field vane test are described: the ordinary field vane test (FVT) and the fast field vane test (FVT-F).The uncertainties of the vane test result are described in Annex D.NOTE 1 This document fulfils the requirements for field vane tests as part of the geotechnical investigation and testing according to EN 1997-1 and EN 1997-2.NOTE 2 This document covers onshore and nearshore field vane testing.
