本文件适用于使用放置在预先存在的钻孔中的圆柱形柔性探头的压力计测试,使用除Menard程序之外的测试程序。
ISO 22476-4提供了遵循Menard程序的压力计测试。
笔记?包含用于测量径向位移的换能器的高压柔性压力计探头也称为柔性膨胀计探头或高压膨胀计探头。
本文件适用于在任何类型的地面上进行的试验,从土壤、处理或未处理的填充物、硬土壤和软岩石,到坚硬和非常坚硬的岩石,无论是在陆地上还是海上。
从该试验得出的参数可以包括刚度、强度、初始地应力状态和固结特性。
This document is applicable to pressuremeter tests using cylindrical flexible probes placed in pre-existent boreholes using testing procedures other than the Menard procedure.
Pressuremeter tests following the Menard procedure are provided in ISO 22476-4.
NOTE?A high-pressure flexible pressuremeter probe which contains transducers for the measurement of radial displacements is also known as flexible dilatometer probe or high-pressure dilatometer probe.
This document applies to tests performed in any kind of grounds, starting from soils, treated or untreated fills, hard soils and soft rocks, up to hard and very hard rocks, either on land or offshore.
The parameters derived from this test can include stiffness, strength, initial in-situ stress state and consolidation properties.
