| 摘 要： | 三峡库区水位上升至175 m之后引发了新的地质灾害,尤其是引起了已发地质灾害的复发。已有研究未考虑周期性浸泡对三峡库区土体性质的影响。采取三峡库区典型松散土体,运用多晶X射线衍射仪对所采取的岩土样在天然状态、长期性浸泡状态、周期性浸泡状态试验工况下的物相进行定性、定量分析的物相变化,得出库区水位升降引起的周期性浸泡作用是导致土体结构和强度劣化的重要因素。

| Abstract: | As the water level of Three Gorges Reservoir has risen up to 175m,it has already caused plenty of geologic disasters,especially caused some occurred disasters to recur.The current researches in this field don't take the influence of cyclical soak on Three Gorges Reservoir's earth into consideration.So the typical loose earth of Three Gorges Reservoir area is adopted,and the earth samples are investigated through a series of tests which are carried out under the condition of native state,long-term soak state... |
