ISO 22476-1:2012涉及设备要求,执行和报告电锥和压电渗透测试,作为根据EN 1997 - 1和EN 1997-2进行岩土勘测和测试的一部分。
在电锥体和压电渗透测试中,锥形穿透测试的两个子类别被考虑:
电锥体穿透试验(CPT),包括锥度阻力和套筒摩擦力的测量;
压电测试(CPTU),其是锥孔渗透测试,附加测量孔隙压力。
CPT执行为像CPT一样,在测量表面上的一个或几个位置测量孔隙压力。
ISO 22476-1:2012规定了以下功能:
锥体穿透试验的类型;
应用类;
穿透深度或穿透深度;
参考基准,锥体穿透试验位置处的地面或水下地面的高程;
相对于可再现的固定位置参考点的锥体穿透测试的位置;
孔隙压力耗散试验
ISO 22476-1:2012 deals with equipment requirements, the execution of and reporting on electrical cone and piezocone penetration tests as part of geotechnical investigation and testing according to EN 1997‑1 and EN 1997‑2.
Within the electrical cone and piezocone penetration test, two subcategories of the cone penetration test are considered:
electrical cone penetration test (CPT), which includes measurement of cone resistance and sleeve friction;
piezocone test (CPTU), which is a cone penetration test with the additional measurement of pore pressure.
The CPTU is performed like a CPT with the measurement of the pore pressure at one or several locations on the penetrometer surface.
ISO 22476-1:2012 specifies the following features:
type of cone penetration test;
application class;
penetration length or penetration depth;
elevation of the ground surface or the underwater ground surface at the location of the cone penetration test with reference to a datum;
location of the cone penetration test relative to a reproducible fixed location reference point;
pore pressure dissipation tests.
