PROBLEM TO BE SOLVED: To provide a simple measurement method capable of simply measuring salinity concentration in soil and easily being performed in a construction site.SOLUTION: Water of fixed capacity is mixed with soil of fixed capacity to be a suspension liquid in which chlorine in the soil is eluted, salinity concentration of the suspension liquid is detected by a simple salinity concentration detection method by a Mohr method, and the salinity concentration in the soil is measured by multiplying the detected salinity concentration by coefficients based on a soil state. For example, the salinity concentration in the soil is measured by multiplication using coefficients: dried soil is 1.0, semidry soil is 1.3, plastic soil is 1.5, and semiplastic soil is 1.8. |
