Description

technical field [0001] The invention relates to the technical field of rolling simulation test systems, in particular to a simulation test system for rolling construction of core wall dam materials in cold regions in winter. Background technique [0002] With the rapid advancement of my country's water conservancy and hydropower projects, the construction of dams has gradually moved closer to the high-altitude mountainous areas in the west. A new batch of high earth-rockfill dam projects represented by the United States (315m in height) have started construction one after another. However, the climatic conditions in cold regions are harsh, and the construction quality control is difficult. The winter construction of these high dams is faced with the challenge of severe cold weather. In the negative temperature environment of the core wall soil, the compaction performance will be reduced due to short-term freezing, and the soil will undergo After repeated freezing and thawing...

Problems solved by technology

However, at this stage, the understanding of the compaction characteristics and working performance of the above-mentioned new filling materials is not sufficient, and the regulations on its scope of application, construction process requirements and related auxiliary construction measures are not clear enough, and corresponding research methods and technologies are lacking.

Conventional laboratory test research cannot reflect the actual rolling process and there is a scale effect; while conducting on-site temperature-controlled rolling tests, it is difficult to control variables, the cost of manpower and material resources is too high, and the test results are highly discrete and reliable. Issues such as low
