| Abstract: | The rock samples,which are collected from the first-stage project field of Funing port in Yunnan Province,are carried out the conventional triaxial compression test after the different numbers of drying and wetting cycles.The mechanical properties parameters variation rule of mudstone and sandstone under the water-rock interaction can be found through the measured rock mechanical properties regression analysis.The continuous damage mechanics approach,based on the elastic modulus,is applied to compare and analyze the deterioration characteristics of mudstone and sandstone.The strength between rock and rock mass has been obtained after engineering conversion of rock mechanic parameters by Hoek-Brown strength criterion.The changing characteristics of overhead sloping type wharf properties have been obtained during the water-rock interaction based on the finite element method. |
| Keywords: | water-rock interaction mechanical properties deterioration overhead sloping type wharf reservoir bank |
