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。
As a mountain city, Chongqing often encounters the treatment of rockfill backfill foundation in the development and construction of the western region. However, due to the fact that the treatment technology of rockfill backfill foundation is not very mature at present, based on the treatment of rockfill backfill foundation in a large mountainous area in Chongqing, combined with the single point ram test results in the field, Ramming method of construction program, the choice of ramming equipment, the choice of ramming energy, packing and filling control methods, and based on a variety of test results of the dynamic compaction effect of a comprehensive evaluation, reached the flotation of ground fill Some of the construction parameters for similar projects provide a reference.
