标准范围

本文件规定了静桩荷载试验的执行规范，其中，单桩承受轴向静荷载压缩，以确定其荷载-位移特性。本文件适用于垂直桩和斜桩。本文件涵盖了所有类型的桩。本文件中考虑的试验仅限于维持荷载试验。本文件不包括恒贯入率桩荷载试验和循环荷载试验。注:本文件拟与EN 1997-1结合使用。EN 1997-1提供了极限状态分项系数和相关系数的数值，以从设计中考虑的静桩荷载试验中得出特征值。本文件提供了执行静态轴向桩荷载试验的规范:a） 检查桩是否符合设计要求；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 compression 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. Pile load tests with constant penetration rate and cyclic load tests are not covered by this document.

NOTE This document is intended to be used in conjunction with EN 1997-1. EN 1997-1 provides 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.

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

a) checking that a pile will behave as designed;

b) measuring the resistance of a pile.
