摘要
CFG桩即水泥粉煤灰碎石桩,它吸收了振冲碎石桩和水泥搅拌桩的优点,充分发挥了桩间土的承载能力。在高速公路软土地基处治中,通常采用振动沉管灌注工艺,其施工工艺简单,处治效果明显,有很高的应用推广价值。
CFG pile, which is short for cement fly-ash gravel pile, absorbs the advantages of vibrating crashed gravel piles and cement mixing piles, and adequately exerts the carrying capacity of soil between piles. In the soft foundation disposal of expressway, the perfusion technique of vibrating immersed pipe which has simple construction technique and prominent disposal effect is adopted corn-monly, thereby it has high value for generalization and application.
