标准范围

本文件规定了在地面灌浆的锚上进行拉力试验的规范，如EN 1997-1和EN 1537所定义。本文件认可三种测试方法。试验方法1涉及循环拉伸荷载，并在荷载阶段测量位移；试验方法2涉及循环拉伸荷载，并在荷载阶段测量荷载损失；试验方法3包括逐步加载，并在连续维持的拉伸载荷下测量位移。本文件提供了实验装置、测量仪器、测试程序、测试结果的定义和表示以及记录内容的规范。注:本文件未提供验证荷载大小和限制标准的规范。这些方面包含在欧洲标准化委员会国家的EN 1997-1或其国家附件中，以及ISO国家本试验标准的类似国家应用文件中。

This document establishes specifications for the execution of tension tests to be carried out on an anchor grouted in the ground, as defined in EN 1997-1 and EN 1537. Three methods of testing are recognized by this document. Test Method 1 involves cyclic tension loading with measurement of displacement at the load stages; Test Method 2 involves cyclic tension loading with measurement of load loss at the load stages; and Test Method 3 involves step-loading with measurement of displacement under successive maintained tension loads.This document provides specifications for the experimental devices, the measurement apparatus, the test procedures, the definition and presentation of the test results and the content of records.NOTE This document does not provide specification for the size of the proof load and the limiting criteria. These aspects reside in EN 1997-1 or its national annex for CEN countries and in similar national application documents for this test standard for ISO countries.
