Design and performance of the Yele asphalt-core rockfill dam
Bibliographic record
Abstract
The planning, design, and performance of the Yele asphalt-core rockfill dam in Sichuan Province, China, are presented. The dam has a maximum height of 124.5 m, is located in a very seismic region with inclement climate, and is founded on a geologically complex foundation, partly resting on a deep and pervious alluvial overburden and partly on bedrock. With these site conditions only an embankment-type dam was considered feasible, and three different options were considered for the design of the impervious barrier: (i) earth core, (ii) concrete facing, and (iii) asphalt core. The third option was chosen. The design is based on extensive analyses and laboratory tests, and a special model test was performed to study the behavior of the connection between the narrow asphalt core and concrete plinth. An impoundment test was performed when the dam was 73 m high to test the imperviousness of the constructed core and the connections between (i) the core and plinth and (ii) the plinth and foundation cut-off wall. An extensive field monitoring program was implemented. Design predictions are compared with field performance observations of the core and its interaction with the adjacent transition zones.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
