钢渣桩在湿陷性黄土地基中的应用探讨

通过钢渣桩在湿陷性黄土中的静荷载试验、土压力调试等试验结果的基础上，对钢渣桩复合地基、桩间土和钢渣单桩的p-s曲线以及其各自的承载力和相应的沉降量进行了分析，探讨了附加应力沿深度变化规律；研究了桩间土承载力、桩土应力比和桩土荷载比的变化规律，对钢渣单桩和碎石柱以及钢渣桩复合地基和石灰粉煤灰桩复合地基等的承载力特性进行了对比分析；对单桩施工影响范围和施工时地基隆起量进行了观测．

Discussion on application of steel slag pile in collapsible loess foundation

The p-s curves of soil around piles and single steel slag pile and the composite foundation and their bearing capacity and their corresponding settlement are analysed using the results of tests Through static load test and soil pressure test of steel slag pile in Collapsible Loess Foundation. The regulation of subsidiary stress with deepth is also analysed and the regulation of bearing capacity of soil around piles and pile soil stress ratio and pile soil load ratio is studied as well. The bearing capacity characters between single steel slag pile and gravel pile and between steel slag pile composite foundation and lime fly ash pile foundation are compared. The monitoring results of the construction effective area of single steel slag pile and the upheaval values of foundation are also analysed.
