南京江北长江阶地区典型地层地基承载力探讨

Discussion on Bearing Capacity of Typical Foundation Soil in North of Yangtze River in Nanjing

地基土承载力的确定方法很多,但各种方法得出的结论差异性较大。以南京江北某雨污分流管线勘察工程为实例,通过大量的原位和室内试验,运用多种方法提出了地基承载力,并进行成果对比,依据地区规范提出了典型地层承载力的建议值。研究结果可对南京江北长江阶地区的岩土工程勘察设计提供参考依据。

The determination for the bearing capacity of foundation soil has many ways ,but the difference between the conclusions from various methods is more big .Here ,taking the investigation for a rain and pollution distributing pipe en-gineering in the north of Yangtze River in Nanjing as an example ,and through a lot of in-situ and laboratory tests ,the suggested values of the typical stratum’s bearing capacity in this area are proposed by using various methods and result comparison .The research result can provide the referent bases for the geotechnical engineering survey and design in the north of Yangtze River in Nanjing .
