| 摘 要： | 对滨海相、河滩相互层土(粘性土、粉砂互层)的工程特性提出了系统认识,从理论上、实践上论证了互层土的稠度指标与现场标准贯入击数不协调的根本原因,并推荐了室内液性指数(IL)作必要折减的修正系数,以此按规范求取地基容许承载力,结果与标贯资料基本吻合。显然,修正后的IL不仅解决了测试指标相互间(IL与N)的矛盾,更重要的是客观上提高了地基强度,简化了施工工艺,产生了十分可观的经济社会效益。

| Abstract: | The author had a systematic knowledge on the engineering characters of the interbedded soils of littoral and river facies like clayey soil and fine sand interbeds,demonstrated theoretically and practically the density index of the interbedded soils and essential reasons for the inharmonious blow of site standard penetration,recommended the correction parameters of liquid index that solved conflicts between the testing targets. |
