摘要
结合南京某钢厂地基处理工程实例,对砂石桩复合地基进行现场和室内土工试验,通过对地基土在处理前后的物理力学性质试验结果的分析对比,研究了砂石桩对吹填砂地基的处理效果,结果表明,经处理后的地基土性指标有所改善,承载力有较大幅度提高。
The densification by sand-rock pile is applied to sandy soil in composite foundation. In a project in a iron and steel company in Nanjin. Observing and surveying the composite foundation was carried out geotechnical lab tests. The physical and mechanics nature before and after the foundation-treatment was analysed.
