| 摘 要： | CFG桩复合地基是软土地基处理中的一种较为有效的方法，近年来得到广泛的应用。通过有限元分析程序对CFG桩复合地基边桩效应进行分析，讨论边桩对CFG桩复合地基沉降、土体应力和承载力的影响。分析表明由于边桩的存在，限制了桩间土体的侧向挤出，减小了土体的竖向位移。同时，边桩增大了附加应力影响范围，能够在一定程度上提高复合地基的承载力，并促进了桩间土承载潜力的发挥。

| Abstract: | GFG composite foundation is an effective method of handling soft ground and is widely applied. Analyzing the side-pile effect of CFG composite foundation by finite element analysis program and discussing the effect of subsidence , stress in soil mass and bearing capacity of the side-pile to CFG composite foundation. The analysis indicates that the side-pile confine the extrusion of soil and diminish vertical displacement. Meanwhile, side-pile augment the effective extension of additional stress, could enhance bearing capacity and promote exertion of the bearing potential of the soil among the piles. |
