粉煤灰砼桩复合路基设计与应用

Composite Subgrade Design and Application of Fly Ash Concrete Pile

随着沿海高速公路的建设,软土路基加固问题日益严重。针对软土路基和粉煤灰砼桩复合路基的工程特性,总结了软土地区砼桩复合地基的承载力和沉降计算方法,并提出了桥台与一般软土路基的搭接过渡段变形协调的设计方法。

With the construction of coastal highway,the problem of soil subgrade strengthening is more and more serious.According to the engineering properties of soft soil subgrade and fly ash concrete pile composite,this paper summed up the soft soil area of concrete pile composite foundation bearing capacity and settlement calculations,and proposed a design approach of making the deformity coordinated by the transition section of the bridge abutment and the general overlap of soft soil subgrade.
