INVESTIGATION OF STRENGTH PROPERTIES OF SALINIZED CLAY SOILS

Каченов В.И., Савченко А.О., Ситева О.С., Алванян А.К.
Mechanical properties of soils are largely determined by the size of their structural elements. However, issues of change in strength saline hydromicaceous clay depending on the concentration threshold Vågå solution studied quite poorly. Conditional design resistance of saline soil can be reduced 1.4-1.8 times during leaching . Under these conditions, additional foundation settlement can be increased by 1.2-1.5 times. Salination clay CaCl2 and NaCl coagulate clay particles, which entails changing the nomenclature of soil , clay loam becomes . With increasing salt concentration in the pore solution clays their grip naturally decreases , and the angle of internal friction , on the contrary , increased. The mathematical models for predicting changes Rowan angle of internal friction and cohesion depending on the degree of salinity of clay with sodium chloride.
