Abstract

The invention provides an earth and rockfill dam material compaction quality evaluation method. The method comprises the following steps: collecting and cleaning data for evaluating dam material compaction quality; obtaining a dry density index reflecting the compaction quality of the dam material; performing correlation analysis on the data for evaluating the compaction quality of the dam body to determine final model input and output parameters; and establishing a compaction quality evaluation model based on deep learning, and evaluating the compaction quality. According to the method, the influence of material source parameters, rolling construction parameters and continuous compaction indexes on the dam material compaction quality is fully considered, a deep learning method is utilized to construct a rockfill material compaction quality evaluation model based on the artificial neural network, the refined real-time quality control of the whole dam filling construction process is realized, human intervention is reduced, the construction quality is ensured, and the time and the cost of dam material compaction quality detection are greatly improved. The method can provide huge application potential and possibility for compaction quality control and engineering quality guarantee of earth and rockfill dam engineering under construction or to-be-constructed.

Description

technical field [0001] The invention relates to a method for evaluating the compaction quality of earth-rock dam materials, in particular, to a method for evaluating the compaction quality of earth-rock dam materials based on deep learning. The invention belongs to the technical field of compaction quality detection of earth-rock dam materials. Background technique [0002] Earth-rock dam is one of the most common dam types in the process of water conservancy and hydropower development. During its filling process, the compaction quality control of the dam material has a decisive impact on the overall quality, safe and stable operation of the dam. If the compaction quality of the dam material is not up to the standard, the dam body may suffer from seepage damage, cracks, landslides and other phenomena, and in severe cases, earth-rock dam failure accidents may also occur. [0003] With the improvement of the intelligent level of dam filling construction, the traditional compa...
