湿陷性黄土地区高层建筑长-短桩复合地基现场试验研究
In-situ Test on Long-short-pile Composite Foundation of High Rise Building in Collapsible Loess Areas
长-短桩复合地基作为一种较为新颖的地基处理形式，在各地工程实践中已有较多应用，但其理论研究水平目前还远落后于工程实践，尤其在湿陷性黄土地区，关于该地基形式的理论和试验研究还较少。本文通过对一工程实例中静载荷试验、桩间土检测和桩体检测的分析，确定了地基承载力特征值，讨论了桩间土和桩体检测结果，得到了长-短桩复合地基荷载与沉降的关系，提出了该地基形式的有关设计建议。
s a new method of groud treatment,long-short-pile composite foundation has been applied extensively in many engineering practices.However,its theoretical level is far below the practical development,especially in collapsible loess areas,its theoretical and experimental study is uncommon.Based on the static load test,surrounding soils and pile-body detection in a practical case,charcteristic value of subgrade bearing capacity,result of surrounding soils and pile-body are presented in this paper.The relation between load and settlement of long-short-pile composite foundation and the suggestion for long-short-pile composite foundation design are proposed.
