摘要
针对 GBJ11-89或 GBJG5 0 0 11-2 0 0 1抗震设计规范液化判别式土层埋深对临界标贯值影响、液化判别等几个方面做了分析 ,并将规范判别式与修正 Seed简化法做了比较。分析结果表明随土层埋深增加临界标贯击数增加是符合液化原理的 ,也不能因为某些极端情况否认规范判别式的正确性
Discussion and analysis are made for the impact of sands depth on critical standard penetration hammer and discrimination of liquefaction, and then the formula of liquefaction discrimination is compared with Seed's simplified procedure. The results are consistent with the liquefaction principle that critical standard penetration hammer increases with the increasing of sands depth, and the validity of liquefaction discrimination formula can't be denied because of some extreme conditions.
