摘要
在处理天然软弱地基过程中,部分土体得到增强或置换,形成复合地基。粉喷桩作为处理软土地基的一种方法,因其造价低廉而在地基处理设计中占有重要位置。对粉喷桩的概念和加固机理进行阐述,探讨粉喷桩的施工工艺,并通过工程实例,对沉降量、早晚期强度、复合地基承载力等检测数据进行分析,证明该加固方法能够提高复合地基强度及地基承载力,适用于软土地基的处理。
Composite foundation refers to the treated soft soil foundation, part oi wmcn nas got strengthened or substituted. ＇As one of the soft soil foundation treament methods, dry jet mixing pile plays an ira portant role for its low building cost. The concept and consolidation reason of the Dry jet Mixing method are described. The technology of the Dry jet Mixing method also are discussed. One project example is gived, the theory is proved that consolidation method can improve road bed compaction degree and applied completely to the soft land base treatment through the analysis on detecting data.
