摘　　要：以省道215乐山五通桥经犍为(高铁站)至沐川快速公路工程犍为段为依托工程,采用碎石桩对K19+975~K20+200航电弃渣场段路基进行处治,并对处治后的复合地基进行了承载能力验算和工后沉降变形验算。由验算结果可知,采用碎石桩进行地基处理,不仅能够大幅提高地基承载能力,还能够有效减少工后变形,从而达到工程要求。Based on the Qianwei section of the provincial highway 215 from Leshan Wutong bridge via Qianwei(high-speed railway station)to Muchuan expressway engineering,the treatment on the subgrade of the K19+975-K20+200 avionics waste slag site section is made by using the gravel piles,and the checking calculation on the bearing capacity of the composite foundation after treatment and post-construction settlement deformation is carried out.According to the checking calculation results,the foundation treatment with gravel piles can not only significantly improve the bearing capacity of the foundation,but also effectively reduce the post-construction deformation,thus meeting the engineering requirements.
