Description
technical field [0001] The invention relates to the technical field of soil compaction degree detection, in particular to an in-situ detection device and method of foundation compaction degree based on a direct current method. Background technique [0002] The degree of compaction refers to the ratio of the dry density of soil or other materials after compaction to the maximum dry density, usually expressed as a percentage, and the maximum dry density is determined by a compaction test. For road engineering, subgrade compaction quality is one of the most important internal indicators of construction quality management. For earth dams, embankments and other projects, the compaction degree of the dam foundation or embankment foundation is an important indicator to ensure that the dam and embankment do not suffer from leakage and damage such as piping and flowing soil. [0003] At present, the detection methods of foundation compaction mainly adopt the ring knife method, the s...
