| 摘 要： | 针对唐山地区岩土勘察及地震工程中剪切波速随深度的经验值尚无通用标准的问题，对规划区209个钻孔剪切波速数据进行研究，通过回归分析法，建立不同地质分区和岩性条件下的回归分析模型，利用决定系数R2检验数据的拟合度，提出研究区的最优回归方程，并利用实际钻孔资料进行验证。结果表明，此次工作建立的回归方程式更准确、精度更高，可成为研究区工程开发建设的重要依据，并在节约成本、缩短工期等方面起到积极作用。

Correlation Analysis of Soil Shear Wave Velocity and Depth in Planning Area of Tangshan City |

| Abstract: | Aiming at the problem that there is no universal standard for the empirical value of shear wave velocity with depth in geotechnical investigation and seismic engineering in Tangshan area, the shear wave velocity data of 209 engineering geological boreholes in the planning area of Tangshan City as the research object was selected,the regression analysis method was adopted, and the regression analysis model under different geological zones and different lithology conditions was established. The fitting degree of the data was tested by the R2 value of the determination coefficient, and the optimal regression equation was proposed in the study area, and the regression equation was verified by the actual drilling data. The verification results show that compared with the two existing models in the research area, the regression equation established in this work is more accurate and has higher precision, which can become an important basis for the development and construction of the research area, and play a positive role in saving costs, shortening the construction period and improving work efficiency. |
