Embodiment Construction

[0018] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below in conjunction with examples.

[0019] According to a typical embodiment of the present invention, a method for evaluating soil corrosivity is provided. The method includes the following steps: 1) determining the measurement index of the soil; 2) segmenting the value of each measurement index, and determining the corresponding score of each segment value; 3) sampling the soil, and determining the value determined in step 1). Measurement indicators; 4) Determine the score according to the value measured in step 3) according to step 2); 5) Calculate the sum of the scores corresponding to each measurement indicator determined in step 4), and evaluate the soil quality according to the calculated results corrosive. The soil corrosivity evaluation method of t...

Abstract

The invention discloses a method for assessing soil corrosivity. The method comprises the following steps: 1) determining measuring indexes of the soil; (2) fragmenting the numbers of each measuring index, and determining the value corresponding to the number in each fragment; (3) sampling the soil, and detecting the measuring indexes determined in step 1); 4) determining the value of the number detected in step 3) according to step 2); and 5) summing the values determined in step 4) and corresponding to each measuring index, and finally assessing the corrosivity of the soil based on the calculating result. By applying the technical scheme of the invention, the technical problems that the large deviation is generated during measuring the resistivity and oxidation-reduction potential of the dry soil with high gravel content and relatively deep water level of groundwater due to the resistance of the gravel to the moving of electrons can be avoided; and compared with a multi-index comprehensive assessment method, the method disclosed by the invention is simpler and more convenient and practical.

Description

technical field [0001] The invention relates to the technical field of soil corrosivity evaluation, in particular to a method for soil corrosivity evaluation. Background technique [0002] In the prior art, the evaluation of soil corrosivity often adopts a multi-indicator comprehensive evaluation method. In this method, various soil physical and chemical indexes are scored, and then the corrosivity grade is evaluated. This method considers too many factors, and it is sometimes difficult to collect them all in practice. [0003] Among them, the multi-indicator comprehensive evaluation method requires the measurement of soil resistivity and redox potential. Soil resistivity measurement is generally done by embedding two electrodes (needles) in the soil. Because moist soil has electrical conductivity, the soil resistivity can be measured by applying a measuring voltage between the electrodes. The oxidation-reduction potential of the soil is to use the reference electrode and ...
