I. Overview
YUC.YJZDK0Type 2-1 Intelligent Equal Strain Control0Measuring the static side pressure coefficient K0values to calculate the stationary earth pressure of the building foundation, the so-called stationary side pressure coefficient K0Value refers to the effective lateral pressure σ of the unit soil under the condition of no lateral deformation3and effective vertical pressure σ1At the same time, according to K0The value can be converted to the Poisson's ratio μ value of soil, that is ,μ= K0/1K +0 , the instrument can realize automatic detection and record K in real time0A new type of special test instrument for geotechnical engineering.
