Demonstration of Engineering Geological Conditions and Optimization of Dam Type in the Dam Site Area of Xiangshui Reservoir
Karst in the dam site area of Xiangshui reservoir is strongly developed,and there may be leakage near the dam bank or around the dam through karst pipelines and fissures.Through the field geological survey and adit drilling survey,this paper demonstrates and analyzes the dam engineering geological conditions in detail from the aspects of dam foundation bearing layer,dam foundation compression deformation,dam foundation(shoulder)anti sliding stability and anti-seepage.The results show that the engineering geological conditions in the dam site area are good,and there are no large-scale adverse geological conditions in the dam site area.After the curtain grouting anti-seepage treatment,the karst leakage channel has good conditions for water storage and reservoir formation,which is suitable for the construction of gravity dam.
