建筑垃圾灰土挤密桩在黄土路基中的设计及应用

介绍建筑垃圾灰土挤密桩地基在黄土路基中应用的作用机理、施工工艺、设计计算、最大干密度和最佳含水率试验及加固效果检测。建筑垃圾灰土挤密桩的应用,能很好地消纳建筑垃圾,并能有效地消除黄土的湿陷性,提高黄土地基的强度,能够满足一般公路路基承载力的设计要求,达到节约资源,减少工程投资的目的,创造显著的社会效益、经济效益和环保效益。

Design and Application of Construction Waste Lime Soft Compaction Piles in Loess Subgrade

This paper has prevented the mechanism of action, construction technology, design and calculation, maximum dry density, optimal water content test and reinforcement effect of the construction waste lime soil compaction pile applied in the loess subgrade. Such compaction pile has such advantages as reuse of construction waste, effectively elimination the collapsibility of the loess, improvement of loess foundation strength, meeting the design requirement for bearing capacity of general road subgrade, achievement of resource saving, reduction of project investment, considerable social benefit, economic benefit and environmental protection benefit.
