| 摘 要： | 针对浅海海域饱和砂土采用标准贯入试验法和抗液化剪应力法进行液化判别分析，对海底浅表层砂土液化判别时，发现对于设计地震第一组、7度和8度条件下，采用《建筑抗震设计规范》（GB50011）2001版推荐的原判别公式比2010版推荐的新公式液化判别结果安全度要高，当工程场地浅表层有砂土分布时，建议采用原判别公式进行液化判别更偏于安全。抗液化剪应力法对海域砂土的液化判别成功率较高，有着较好的适宜性，是值得推广应用的液化判别方法。

| Abstract: | By analyzing the seismic liquefaction of the saturated sandy-soil in the epicontinental sea area by the standard penetration test （Strl＂） method and the anti-liquefaction shear stress （ALSS） method, it is found that, for theliquefaction evaluation of shallow sandy-soil in maritime engineering site （ design earthquake group 1 , seismic precautionary intensity being 7 （ 0. 10g ） or 8 （ 0. 20g ） ） , theliquefaction evaluation formula recommended in ＂Code for seismic design of buildings＂ （ GBS0011--2001 ） is more safety than the new one recommended in ＂Code for seismic design of buildings＂（GBS0011--2010）. The oldliquefaction evaluation formula is suggested due to its safety for the condition of shallow sandy-soil distribution in construction sites, ALSS with high success rate and suitability for theliquefaction evaluation of sandy-soil in maritime engineering site is worth popularization. |
