Pressuremeter/menard Pressuremeter Electronic C TECH CN;HEB PY

Product Overview

Description

Pressuremeter/Menard pressuremeter:

Pressuremeter test according to EN ISO 22476-4 and ASTM D-4719-00 Standards.

Test Description:

A pressuremeter test is an in-situ stress controlled loading test performed on the wall of a borehole using a cylindrical probe which can expand radially.

For the test readings (volume variation based on controlled pressure), a stress-strain curve can be obtained, in the case of plane deformation, which yields:
-the Menard pressuremeter modulus
-the creep pressure
-the Menard limit pressure
