Blasting compaction combined dynamic compaction foundation treatment method
The invention belongs to the field of foundation treatment, and discloses a blasting compaction combined dynamic compaction method foundation treatment method. The method comprises the following stepsof 1) determining the number of stratified treatment layers according to the geological condition of a site, the treatment depth and the bearing capacity requirement after treatment; 2) determining the explosive point distribution form, the burial depth and the explosive amount of each point of each layer under a top layer according to the geological condition of the site, the treatment depth andthe bearing capacity requirement after treatment; and 3) determining a top layer point compaction point distribution form, an energy level and the compaction frequency of each point according to thegeological condition of the site and the bearing capacity requirement after treatment. According to the method, the blasting technology and the dynamic compaction technology are combined for land areafoundation treatment, a large-area deep backfill site can be treated, long-term settlement is rapidly reduced, the bearing capacity is increased, and meanwhile, compared with a traditional method, the method has the advantages that the construction speed is high, the cost is low, the economic problem of large-area deep backfilling and deep soft soil foundation treatment is solved, meanwhile, thetreatment effect is not influenced by the treatment depth, the engineering treatment depth and treatment speed are greatly improved, the engineering cost is reduced, and the method is applied to landarea foundation treatment.
本发明属于地基处理领域，公开了爆破挤密联合强夯法地基处理方法，包括以下步骤：1）根据场地地质情况、处理深度、处理后承载力要求确定分层处理层数；2）根据场地地质情况、处理深度、处理后承载力要求确定顶层下每层炸药布点形式、埋深、每点炸药量；3）根据场地地质情况、处理后承载力要求确定顶层点夯布点形式、能级及每点夯击次数，本发明将爆破技术与强夯技术结合进行陆域地基处理，能处理大面积深回填场地，快速降低远期沉降、增加承载力，同时该方法与传统方法相比施工速度快，费用低，解决了在大面积深回填及处理深层软土地基的经济问题，同时处理效果不受处理深度影响，大大提高工程处理深度、处理速度，降低工程造价，应用到陆域地基处理。
