Abstract

The backfill soil in the reservoir area has engineering properties such as high liquid limit, high plasticity index and high water content, so it is difficult to determine the key construction parameters. Combining the nuclear densimeter method and sand filling method, through the indoor compaction test and field compaction test, the relationship between dry density and moisture content, dry density and rolling times, compaction degree and rolling times is analyzed, and the dry density measured by different test methods is fitted and analyzed, so as to determine the construction parameters such as the paving thickness, moisture content, compaction equipment and rolling times of backfill soil. The test results show that when the loose paving thickness is 35 cm and the rolling times is 6, the soil moisture content is between 28.0% and 28.6%, and the compaction degree is 98.9% and 99.5%, which meets the requirements of reservoir filling construction. The moisture content and compactness of soil measured by nuclear densimeter method and sand filling method are close to each other. The test results have a strong correlation, and the determinable coefficient reaches 0.94, which verifies the reliability of the two test methods. The research results have important reference value and scientific significance for guiding the selection of backfill and filling construction in the reservoir area.
