FIELD: construction industry. SUBSTANCE: for determination of adhesion of soils for evaluation of their long-term strength tests are conducted of soil samples with undisturbed composition for shear and ball former block and of samples of same soil with undisturbed and disturbed composition for free swelling. By results of measurement of parameters of tests structural adhesion of soil is determined which takes into account total adhesion obtained in test for shear, share of cementing and coagulation structural bonds found by data of tests for swelling and decreased adhesion of soil due to disturbance of cementing bonds during investigation period by data of tests with ball former block. EFFECT: improved authenticity of method. 5 dwg
