| Abstract: |
| According to the updated information of site investigation, site dry density, water content, gravel gradation, laboratory and site seepage experiments, and large scale triaxial experiments of Gouhou dam materials, the authors analyze the physical and engineering behavior of the dam gravel materials. The findings are the important bases for further understanding the breach mechanism of the dam. |
