| 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.

| Abstract: | 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... |
