摘　　要：随着水环境治理工程的不断发展,整治内容已由前期单一的管网建设逐步扩展到包含河道综合整治在内的系统性工程,而河道综合整治离不开岸坡挡墙设计及施工。由于靠近河道,长期受到河水浸泡影响,河堤挡墙基础一般比较软弱,为满足施工安全、质量要求,河堤挡墙基础需进行一定处理。以石马河流域综合治理工程樟木头镇挡墙的基础换填处理工艺为研究对象,结合现场实际情况分析沿河道的挡土墙在地下水丰富的情况下的基础换填处理施工工艺流程,总结现场施工的技术要点。With the continuous development of water environment treatment project,the content of regulation has gradually expanded from single pipe network construction to systematic engineering including comprehensive river regulation.The design and construction of bank slope retaining wall is indispensable for comprehensive river regulation.As it is close to the river,the foundation of embankment retaining wall is generally weak due to long-term immersion.To meet the requirements of construction safety and quality,the foundation of embankment retaining wall needs to be treated.Taking comprehensive treatment project of Shimahe Basin as the research object,the construction process of foundation filling treatment of retaining wall along the river in the case of abundant groundwater is analyzed in combination with field conditions,and the technical points of field construction are summarized.
