GOST 30672-2012 PDF

Full title and description

ГОСТ 30672-2012 — Грунты. Полевые испытания. Общие положения. (English: GOST 30672-2012 — Soils. Field testing. General provisions.) The standard establishes general requirements for methods, equipment and procedures used for in‑situ (field) determination of physical‑mechanical properties and the state of soils when performing geotechnical investigations for construction.

Abstract

GOST 30672-2012 defines the scope, general principles and mandatory requirements for carrying out field tests on soils used in design and construction. It describes types of in‑situ tests, instrumentation and basic measurement procedures for assessing moisture, density, permeability, strength, deformability, frost behavior and bearing capacity of soils. The document serves as a normative baseline for planning, performing and documenting geotechnical field investigations.

Scope

The standard applies to field (in‑situ) methods used to determine physico‑mechanical properties and current state of natural, engineered and frozen soils in the context of site investigation for construction works. It gives general requirements for selection of field methods, preparation of test locations, use and calibration of instruments, measurement procedures, recording of results and reporting so that field test data are suitable for engineering interpretation and design.

Key topics and requirements

• Classification and purpose of field methods for soil investigation (dynamic and static probing, sounding, plate and pile tests, permeability, moisture and density measurements).
• Requirements for test equipment, installations, sensors and their calibration and verification before use in the field.
• Procedures for preparing test sites, carrying out measurements and controlling test conditions (water table, temperature, disturbance minimization).
• Methods for determining moisture content, bulk/dry density, permeability (filtration), seasonal frost depth and temperature of soils.
• In‑situ strength and deformability testing: static and dynamic probing, cone and friction measurements, shear resistance tests and pile load tests.
• Recording, processing and presentation of field data, including required metadata (location, depth, equipment, environmental conditions) for engineering use.
• Recommendations on method selection depending on soil type, degree of coarse inclusions and frozen/seasonal conditions.

Typical use and users

Used by geotechnical and site investigation engineers, engineering surveyors, construction designers, testing laboratories and regulatory bodies involved in pre‑construction site investigation, foundation design, road and earthworks projects, and analysis of frost and settlement risks. Also used by organizations preparing geotechnical reports and by manufacturers/suppliers of field testing equipment to ensure compliance with national practice.
