摘要
针对宿州市北部第四系土层进行分层并研究各层的工程特性,可以为研究区内工程建设提供良好的理论基础。在区域内第四系土层中采取样品并结合土工试验对目标层位的物理力学性质进行研究,结果表明:研究区内土层共分4层,其中1、3、4层为粉质壤土,具有微透水性,压缩性中等且孔隙度较小进而判断密实度较好。根据地震基本烈度数据判断地基可不进行液化判别和处理且承载力较高,第2层为砂壤土,具中等透水性且有孔隙承压水赋存其中,地基土易产生渗透变形影响基础稳定,建议对地基土进行防渗、抗冲处理。
The stratification of the Quaternary soil layers in northern Suzhou city and the study of the engineering characteristics of each layer can provide a good theoretical foundation for engineering construction in the study area. The physical and mechanical properties of the target horizon are studied by means of taking samples and combining geotextile test in the Quaternary soil layers. The results show that the soil layer in the study area is divided into 4 layers, of which first, third, fourth are silty loam, with micro permeability, moderate compressibility and small porosity, and the density is better. The foundation may not be liquefied and high bearing capacity according to the basic seismic intensity data, the second layer is sandy loam, medium permeability and pore confined water in the soil is easy to produce effect of seepage deformation stability of foundation and suggestions on soil seepage, anti shock treatment.
