Geotechnical Investigation and Testing - Field Testing - Part 11: Flat Dilatometer Test
Also Known As:
The DIN EN ISO 22476-11 standard provides guidelines and requirements for conducting ground investigations using the flat dilatometer test (DMT). The test is performed as part of geotechnical investigation services, following the specifications of EN 1997-1 and EN 1997-2.
The standard defines the principles and procedures for conducting the DMT to evaluate the mechanical properties of soil and rock formations. It outlines the equipment and instrumentation required for carrying out the test, as well as the calibration procedures to ensure accurate and reliable results.
Furthermore, the standard provides guidance on the interpretation of DMT results and the determination of key geotechnical parameters such as soil stiffness, strength, and deformability. It also discusses the limitations and uncertainties associated with the test method and offers recommendations for handling challenging soil conditions or special testing circumstances.
