摘要
通过钢渣桩在河南某地湿陷性黄土中的静荷载试验、土压力测试等试验的试验结果,对钢渣桩复合地基、桩间土和钢渣单桩的p-s曲线、附加应力沿深度变化规律进行了分析;研究了桩间土承载力、桩土应力分担比、桩土荷载分担比的变化规律,对钢渣单桩和碎石桩以及钢渣桩复合地基和灰沙桩复合地基等的承载力特性进行对比和分析,并对钢渣桩复合地基的环境效应进行了探讨,得出了有益的结论。
In this paper, based on the results of static load test and soil pressure test of steel slag pile in collapsible loess foundation some where in Henan Province, the p-s curves of soil around piles and single steel slag pile and the composite foundation are analyzed. The rules of variation of subsidiary stress with depth are analyzed as well. The rules of variation for the bearing capacity of soil around piles, pile-soil stress ratio and pile-soil load ratio are studied. The bearing capacity characters of single steel slag pile are compared with those of gravel pile as well as steel slag pile composite foundation compared with lime stone pile foundation. The environment effect of steel slag pile composite foundation is also discussed. Some useful conclusions are given.
