Abstract
The invention is applicable to the technical field of civil engineering, and provides a method for testing the moisture absorption water content of soil. The method comprises the steps of acquiring the weight of an empty weighing container; selecting a soil sample and putting into the empty weighing container, and carrying out moisture absorption treatment on the soil sample; acquiring the weight of the weighing container which contains the soil sample subjected to the moisture absorption treatment; drying the soil sample subjected to the moisture absorption treatment, and acquiring the weight of the weighing container which contains the dried soil sample; determining the moisture absorption water content of the soil sample according to the weight of the empty weighing container, the weight of the weighing container which contains the soil sample subjected to the moisture absorption treatment and the weight of the weighing container which contains the dried soil sample. After the method is adopted, the problem that in the prior art the method for judging whether a soil sample belongs to expansive soil or not by visually determining the color of the soil sample is easily influenced by subjective factors of engineering personnel and is not accurate in basis for determination, thus easily causing misjudgment can be solved under the premise of not increasing instruments or laboratory rooms.
Description
technical field [0001] The invention belongs to the technical field of civil engineering, in particular to a method for testing moisture absorption and water content of soil. Background technique [0002] Soil can be divided into expansive soil and non-expansive soil according to its moisture content. Especially for highway civil engineering, expansive soil expands due to water absorption, loses water and shrinks, and its performance is extremely unstable, which is likely to cause instability of the roadbed, and in severe cases, it will cause irreparable damage to the roadbed. In order to maintain the stability of the subgrade and ensure road safety, it is necessary to sample the soil in the project before construction, and judge whether the soil sample belongs to expansive soil. [0003] At present, the traditional method of discriminating soil samples generally judges whether the soil samples belong to expansive soil by visually inspecting the color of the soil samples by...
