旋喷注浆法加固软土地基试验研究

Field Test of Rotary Jet Grouting Pile on Soft Ground

试验研究中，对成桩前后桩间土的物理力性质进行了常规测试，桩间土在旋喷成桩后，其密实度有所提高，由桩土共同作用组成的复合地基承载力也相应得到提高。含钢筋旋喷桩比不含钢筋旋喷桩的垂直及水平承载力均提高３３％以上。

This papre presented the behavior of rotary jet grouting pile on soft ground.The field test showed that the density of soil at the pile end could be increased, the bearing capacity of composite ground consisting of the pile and soil could also be increased.Vertical and lateral bearing capacity of the reinforced rotary jet grouting pile would be increased by 33% or more in comparison with that of the unreinforced rotary jet grouting pile.
