标准摘要
[中文适用范围]： 本文件适用于使用梅纳德程序以外的测试程序将圆柱形柔性探头放置在现有钻孔中的压力计测试。 ISO 22476-4 中提供了遵循梅纳德程序的压力计测试。 注：包含用于测量径向位移的传感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测试，从陆地或海上的土壤、经过处理或未经处理的填充物、硬土和软岩石，一直到硬和非常硬的岩石。 从该测试得出的参数可以包括刚度、强度、初始原位应力状态和固结特性。 [外文原描述]： 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.
