基于标准贯入及土工试验的伊拉克哈法亚油田地基承载力回归分析

通过对伊拉克哈法亚油田的地基土进行载荷试验、标准贯入试验及室内土工试验,根据回归分析理论,得到了基于标贯试验击数N、土工试验参数(包括含水率ω、密度ρ、塑性指数Ip、孔隙比e)的地基承载力回归方程.根据上述研究结果,当该区域没有条件进行载荷试验时,可以利用原位测试和土工试验的结果确定地基承载力.由于美索不达米亚平原区域地质条件相似,该文的研究成果对于确定美索布达米亚平原区的地基承载力具有参考意义.

Regression Analysis of Foundation Bearing Capacity of Iraq Halfaya Oilfield based on Standard Penetration Test and Soil Test

Through the load test,standard penetration test and indoor soil test on the foundation soil of Iraq Halfaya oilfill,and according to the regression analysis theory,the regression formula of foundation bearing capacity is obtained based on the number of standard penetration test blows N,parameters of soil test(including moisture content ω,density ρ,plasticity index Ip,void ratio e).According to the above research results,when that area doesn't have the condition for load test,the foundation bearing capacity can be determined by the results of the in situ test and soil test.Because the geotechnical conditions are similar in the Mesopotamia plain area,the research results in this paper have reference value on determining the foundation bearing capacity of Mesopotamia plain.
