摘要
通过钢渣桩在湿陷性黄土中的静荷载试验、土压力测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 ,对钢渣单桩和碎石桩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 ;
The p-s curves of soil around piles and single steel slag pile and the composite foundation and their bearing capacity and corresponding settlement are analysed using the results of static load test and soil pressure test of steel slag pile in Collapsible Loess Foundation. The subsidiary stress regulation is also analysed, and the bearing capacity regulation of soil around piles, pile-soil stress ratio and pile-soil load ratio is studied. 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 effective area of single steel slag pile and the upheaval values of foundation during construction are also analysed.
