标准范围
本文件规定了设备要求、梅纳德旁压试验的执行和报告。本文件描述了在陆地或海上的天然地基、经处理或未经处理的填料中进行梅纳德旁压试验的程序。本文件的旁压试验结果适用于地面强度和变形参数的定量测定。在创建钻孔时(根据ISO?22476),它们可以产生随钻测量的岩性信息-15). 它们也可以与直接调查相结合(例如,根据ISO?22475-1进行取样),或与其他原位测试相比较(见EN?1997-2)。
This document specifies equipment requirements, the execution of and reporting on the Ménard pressuremeter test.This document describes the procedure for conducting a Ménard pressuremeter test in natural grounds, treated or untreated fills, either on land or off-shore.The pressuremeter tests results of this document are suited to a quantitative determination of ground strength and deformation parameters. They can yield lithological information in conjunction with measuring while drilling performed when creating the borehole (according to ISO 22476-15). They can also be combined with direct investigation (e.g. sampling according to ISO 22475-1) or compared with other in situ tests (see EN 1997-2).
