摘要
通过现场标准贯入试验,对国道317线K205＋700~K207＋100段路基填方段中的淤泥质粉细砂层进行了液化判别。《公路工程抗震设计规范》（JTJ004-89）和《建筑抗震设计规范》（GB5001-2001）的计算结果均表明该砂层会产生液化。但前一规范的计算值偏大,在工程中建议使用后一规范,并以振冲密实法进行预防。
Field standard penetration tests were conducted to decide on the liquefaction of the layer of fine silt sand in Section K205 ＋700 ~ K207 ＋100 of State Road 317.Values were calculated by both ＂Code for Seismic Design of Highway Engineering＂（JTJ004-89） and ＂Code for Seismic Design of Buildings＂（GB5001-2001）.Both results showed the probability of liquefaction.But,with the value by the former code too big,the latter one is recommended in the engineering project and vibro-compaction method is proposed for prevention.
