标准摘要
[中文适用范围]： 该文件适用于使用phi计程序进行的孔隙比剪切试验，通常称为phi计试验（从摩擦角phi、黏聚力co和测量meter派生而来）。该试验可以在所有类型的天然土、填土和人工土中进行，这些土壤可以是饱和或非饱和的。它不适用于非常软细粒土、非常松散粗粒土、中等到极硬岩石以及以大于150 mm直径卵石为主的天然或人工土。通常，在其原位抗剪特性数量级为以下范围内的土壤中适用：——Ménard压力计极限压力：约0.4 MPa < plM < 3.5 MPa 或在颗粒非黏性土中超过4 MPa；——CPT圆锥阻力：1.5 MPa [外文原描述]： This document is applicable to the borehole shear test using the phicometer procedure, commonly named the phicometer test (etymologically derived from phi for friction angle, co for cohesion and meter for measurement). The test can be performed in all types of natural soils, fills and artificial soils, which can be saturated or not. It does not apply to very soft fine soils, very loose coarse soils, medium strong to very strong rocks and natural or artificial soils with a predominance of cobbles having a particle diameter greater than 150 mm. Generally, the test is applicable in soils with an order of magnitude of their in situ resistance characteristics as follows: — Ménard pressuremeter limit pressure: 0,4 MPa < p lM < 3,5 MPa approximately or more than 4 MPa in granular non-cohesive soils; — CPT Cone resistance: 1,5 MPa <qc <15 MPa approximately, depending on the type of soil (see Annex E); — SPT N: 8 <N <50 approximately, depending on the type of soil (see Annex E). The test can also be carried out in soils presenting a resistance outside these application limits as long as the representativeness of the results is assessed or validated by the analysis of the PBST graphs (see Clause 8). This document applies only to tests carried out at a depth less than or equal to 30 m. The parameters derived from this test are the shear strength properties, as the cohesion and angle of friction.
