EXPERIMENTAL SET TESTING GROUND BY METHOD OF SINGLE-AXIS COMPRESSION

摘要

FIELD: study of rheological properties of grounds in laboratories. SUBSTANCE: salient feature of invention lies in that proposed experimental set testing ground by method of single-axis compression has leak-proof section of tube in which specimen with cross-section area up to 2500 sq cm and ratio of diameter d to height h from 1:2 to 1:5 loaded by piston with holes is placed. Hydraulic lock in the form of water column is located above piston, blank plug through which rod with rubber collar for piston loading passes is placed above it. Tube to change height of hydraulic lock comes out of blank plug. Technical result of invention consists in provision for simulation of depth of water-saturated two-phase specimen of ground from day surface and study of effect of void water in time. EFFECT: improved authenticity of testing. 1 dwg
