石灰粉喷桩在软基处理中的应用

Lime Dust Spray Technique for Soft Foundation Disposal

粉喷桩是目前国内外常用的一种深层加固处理软土技术,结合石灰粉喷桩加固软土地基的原理在高速公路软基处理中的应用。从设计、机械设备、施工方法、应用效果等方面,介绍石灰粉喷桩施工技术,并对比地基加固前后的物理力学性质指标,具体评价和论证了石灰粉喷桩对加固地基,提高地基承载力的作用。

Lime dust spray is a technique for deep layer soft soil reinforcement in common use domesti- cally and overseas. This paper introduced the technique of lime dust sprayer in construction in design, equip- ments, operation and effects, and study the physical and mechanical data between foundations with and with- out the technique to bring out its advantage and weakness.
