摘　　要：重庆作为一个山地城市,在西部大开发建设中,经常遇到块石回填土地基的处理。但是由于目前块石回填土地基的处理技术不是很成熟,本文以重庆某开发项目大型山区块石回填土地基处理为依托工程,结合现场单点夯试验结果,提出了在块石地基处理中强夯法的施工方案、夯击设备的选择、夯击能的选择、填料和堆填的控制方法,并根据各种检测结果对强夯法效果进行综合评价,得出了块石填土地基处理的一些施工参数,为类似工程提供参考。The treatment of block stone filling foundation often occurs in the construction in Chongqing which is a hilly city. The treatment technique for the block stone filling foundation is not mature at present. Through certain project with the treatment of block stone filling foundation in Chongqing, the construction scheme of dynamic compaction method （ DCM）, the selection of the equipment and the tamping energy, and the control process of the filling are put forward based on the results from the in-situ single-point testing with DCM. The effect of the treatment with DCM is evaluated based on the different inspection results, and some construction parameters for the foundation treatment are obtained, which could give a reference for the similar projects.
