标准范围

本文件规定了静桩载荷试验的执行规范，在静桩载荷试验中，单桩承受拉伸轴向静载荷，以确定其载荷-位移行为。本文件适用于垂直桩和耙桩。本文件涵盖所有类型的桩。本文档中考虑的测试仅限于维持负载测试。本文档不包括循环载荷试验。笔记？伊索？22477-2旨在与EN？1997-1.EN？中提供了极限状态部分因子的数值和从静桩荷载试验中导出特征值的相关因子的数值，这些特征值将在设计中考虑。1997-1.本文件提供了进行静力轴向桩载荷试验的规范:A）？检查桩的行为是否如设计的那样，b）？测量桩的阻力。

This document establishes the specifications for the execution of static pile load tests in which a single pile is subjected to an axial static load in tension in order to define its load-displacement behaviour.

This document is applicable to vertical piles as well as raking piles.

All types of piles are covered by this document. The tests considered in this document are limited to maintained load tests. Cyclic load tests are not covered by this document.

NOTE            ISO 22477-2 is intended to be used in conjunction with EN 1997-1. Numerical values of partial factors for limit states and of correlation factors to derive characteristic values from static pile load tests to be taken into account in design are provided in EN 1997-1.

This document provides specifications for the execution of static axial pile load tests:

a)       checking that a pile behaves as designed,

b)       measuring the resistance of a pile.
