摘要
本文针对目前粉喷桩复合地基普遍存在的桩体强度偏低或复合地基沉降过大的问题 ,结合浙江宁波地区的实际情况 ,进行了大量的室内水泥土试块试验 ;并以沉降为控制指标 ,研究了在水泥中掺入粉煤灰的粉喷桩加固土复合地基的最优桩长和最优置换率问题 ;
In this paper, to improve the strength of the churning pile and control the settlement of churning pile composite foundation, a large number of specimens of cement and fly ash strengthened soil were tested in the lab with the consideration of Ningbo geological conditions. From the research, the optimizing amount of cement and fly ash treated churning pile, the optimizing length of pile and replacement ratio in the composite foundation were studied according to settlement control. Finally, an actual engineering example was analyzed for the feasibility of the application.
