摘　　要：济南市小清河综合治理工程(水利工程部分)的钢筋混凝土岸墙坐标位置的地基承载力不能满足设计要求,经多方案比选、现场试验和经济效益考虑后确定采用抛石干铺法处理地基,施工从试验段获取技术参数到抛石基础的全面施工,通过检验检测、对比分析各试验数据的可行性,最终确定了施工工艺和质量控制方法,并形成了作业技术指导书,经承载力检测、沉降位移观测。该方法施工简便、经济安全、质量保证、施工周期短,同时为类似工程提供了可借鉴的施工数据和经验。The foundation bearing capacity at the coordinate position of the reinforced concrete quay wall of the Xiaoqing River Comprehensive Treatment Project in Jinan City(part of the water conservancy project)cannot meet the design requirements.After multiple scheme comparisons,field tests and economic benefits,it is determined that the rubble dry paving method is used to treat the foundation,Construction from the test section to obtain technical parameters to the full construction of the riprap foundation,through inspection,comparison and analysis of the feasibility of the test data,the final determination of the construction process and quality control methods,and the formation of operating technical instructions,the bearing capacity Detection,settlement and displacement observation,the construction of this method is simple,economical and safe,quality assurance,and short construction period.At the same time,it provides construction data and experience for similar projects.
