摘要
对阿什贡电站坝址区砂性土层存在的砂土振动液化问题进行分析,对泄水闸地基采用振冲碎石桩处理,对船闸地基采用高压旋喷桩处理,对左岸土石坝段进行回填压盖处理,并对压盖后的坝基砂性土层进行抗震复核计算,以论证该处理方案在理论上的可行性。
The vibration liquefaction of sand at dam site area of Ashigong hydropower station was analyzed in the paper,the foundation of discharging sluice was treated by using vibro replacement stone column,and the foundation of navigation lock was treated by high pressure jet grouting pile,the left-bank earth-rock dam was treated by backfilling and gland.Antiseismic calculation of sand at dam foundation after backfilling and gland was conducted,which proves that the treatment was effective in the theory.
