High-water-content clay dynamic compaction replacement filling foundation and construction method thereof
The invention discloses a high-water-content clay dynamic compaction replacement filling foundation and a construction method thereof. The construction method comprises the steps that high-water-content clay with the natural water content being above 45% is taken as basic padding, hard aggregate serves as a replacement material, a dynamic compaction replacement method is adopted for carrying out reinforcing construction in a layered manner, layer-by-layer construction is carried out from bottom to top to obtain the filling foundation, before reinforcing construction of each layer is carried out, the high-water-content clay is directly backfilled to a reserved virtual laying thickness of the corresponding layer, the filling foundation is manufactured through the method, the filling foundation constructed with the high-water-content clay as the padding can meet the current engineering technical standards and the engineering use needs, meanwhile, measures like airing do not need to be taken to reduce the water content of the high-water-content clay in advance, the construction period can be effectively shortened, the incomes from investment can be improved, in addition, the method canavoid difficult paving and mixing brought by too wet caking characteristics of the high-water-content clay, and the construction efficiency is greatly improved.
本发明公开高含水量黏土强夯置换填方地基及其建造方法，所述建造方法以天然含水量在45％以上的高含水量黏土为基础填料并以硬质骨料为置换料，采用强夯置换法分层进行加固施工并且由下至上逐层建造获得填方地基，其中，在每层加固施工之前一次性地将高含水量黏土直接堆填至该层的预定虚铺厚度。所述填方地基则采用上述方法制得。本发明使得以高含水量黏土为填料建造的填方地基能够满足现行工程技术标准和工程使用的要求；同时无需采取晾晒等措施事先降低高含水量黏土的含水量，能够有效节省施工工期并提高投资收益；此外，该方法还可以避免高含水量黏土的过湿结团特性带来的摊铺、拌和困难，大幅提高施工效率。
