【摘要】 通过国道GZ40西安至潼关高速公路K34～K76段部分路段工程实例,简单介绍了一种利用干拌水泥混凝土夯扩桩进行路基加固的技术特点、施工工艺、受力机理及其在实际应用中需要注意的一些问题。结果表明:工程采用C20干拌水泥混凝土夯扩桩对该路段路基进行了加固,加固后的路段路基未出现新的沉陷,这说明加固工程取得了预期的效果。更多还原

【Abstract】 This paper simply introduces the technical characteristics, construction craft, and stress-mechanics of dry-mixed cement concrete ram-expanded pile in foundation reinforced, and the problems for attention in actual engineering projects of Xitong highway. The project adopted C20 dry-mixed cement concrete ram-expanded pile,the reinforced road has not appeared new sinkage. The foundation project has gained anticipated result.更多还原
