气浆振冲注浆法原理探讨

Discussion on the principle of jet-vibra grouting

软土处理发展至今,现有各种工艺均较为成熟,然而都有各自的局限性,无法更广泛地适应复杂多变的土层。为在处理效果上有更大提高,施工设备有更大的适用范围,探讨了基于振冲法及高压喷射注浆法而改进后的气浆振冲注浆法的工作原理、工艺参数、气浆振冲注浆法用于地基处理时复合地基承载力估算方法,以及气浆振冲注浆法原理及工艺有待完善的地方,可供实际工程设计及施工参考。

Since its high maturity process,the soft soil treatment methods have their limitations respectively.A single method can＇t be aplied to complex geotechnical environment.For improving the treatment effects and getting a wide applicability of a single equipment,the jet-vibra grouting,that was based on the vibraflotation and jet grouting,has been discussed.Its working principle,technological parameter have been presented tentatively and in turn,the bearing capacity of composite foundation estimation theory has been analysed while the jet-vibra grouting being used to foundation treatment.
