【摘要】 石佛寺水库是辽河干流的一座重要水库。前期的地质勘察发现主坝坝基存在有较严重的地震液化现象,据此运用标贯法和seed简化方法进行了坝基的抗震液化分析判别。根据石佛寺水库的特定条件和具体情况,本文提出了采用以振冲法为主并结合振动沉管砂桩法处理主坝坝基的地震液化问题。根据现场试验,此种治理方案效果明显,具有较强的应用性和推广性。更多还原

【Abstract】 Shifosi reservoir is an important reservoir of Liaohe main stream.By geological investigation,it is found that the problem of serious earthquake liquefaction existed at the dam foundation.With use of standard penetration test and seed method,the analy-sis on dam foundation anti-earthquake liquefaction was done.According to the specific conditions of Shifosi reservoir,the paper proposed the treatment method of vibroflotation combined with vibrosinking.The site experiment result showed that the method was effective and worthy popularization.更多还原
