黄河沿岸砂土场地工程地质特征及拟建物基础类型选择

Engineering Geological Features of Sand Site and Selection of Construction Base Type Alongside Yellow River

通过野外钻探取样编录,对场地地层进行划分,在此基础上利用室内土工试验、现场标准贯入试验、重型动力触探等成果资料进行数理统计及相关计算,结合有关规范与工程地质手册,给出了内蒙临河区某工程地基承载力的推荐值和设计需要的相关参数建议值。并且对地基土进行工程地质条件评价、持力层选取、地基处理方式提出建议,为本工程施工图设计提供了可靠的地质资料。通过根据岩土工程勘察报告和实际施工情况,分析、阐述了内蒙临河地区地基土工程地质特征及地基基础处理建议,为类似工程提供参考。

The field stratigraphic division was made through field sample drilling logging. On this basis,and adoption of indoor geotechnical tests and in-situ standard penetration test,and heavy dynamic penetration results data,in combination with the relevant specification and engineering geology manuals,mathematical statistics and calculation were carried out,and the recommended values of the foundation bearing capacity and relevant design parameters in one project in Linhe district of Inner Mongolia were proposed. Proposals were made further on the evaluation of the engineering geological conditions,bearing layer selection,and foundation treatment recommendations for the foundation soil,providing for the engineering construction drawing design with reliable geological data information. According to the geotechnical engineering investigation report and the actual construction situation,analysis is made on the engineering geological characteristics of foundation soil in Linhe,Inner Mongolia and foundation treatment suggestions were made for reference.
