文章针对石佛寺水库泄洪闸闸基下存在的砂基液化,进行了混凝土灌注桩和振冲碎石桩两个方案的分析论证,认为这两种方案在技术上都可行。在特殊荷载组合下,灌注桩方案桩基侧移可能不满足要求,而振冲碎石方案抗震性能好,施工速度快,工期短,投资少,应予优先考虑 In the light of the sand-based liquefaction existing at the base of Shifusi reservoir sluice sluice gate, two schemes of concrete pouring pile and vibrating stone column were analyzed and argued. Both of them are technically feasible. Under the combination of special load, the displacement of pile foundation of cast-in-place piles may not meet the requirements, while the vibration-broken gravel program has good seismic performance, fast construction speed, short construction period and less investment, and should give priority to
