Composite treatment construction method for mountain highway high-fill roadbed valley soft soil interlayer foundation
The invention discloses a mountain highway high-fill roadbed valley soft soil interlayer foundation composite treatment construction method. The method comprises the following steps of construction preparation, site rechecking, soil replacement, cultivation and planting, dynamic compaction construction, drainage construction and completion acceptance. In the construction process, cultivation and planting soil is replaced and filled with hard rock blocks, so that a replacement layer becomes a water seepage layer, and the drainage speed of a fill roadbed base is increased in cooperation with a water separation belt and a blind ditch; moreover, the first gravel soil layer and the clay layer are subjected to composite reinforcement treatment through dynamic compaction construction, gaps and moisture stored in soft soil particles and among the particles are discharged, and the compactness, the C value and the phi value of the soil layer are improved; meanwhile, the hard block stones are compacted and embedded into the first gravel soil layer even the clay layer through dynamic compaction, the first gravel soil layer and the clay layer are compacted and reinforced, and the gravel soil, the clay and the hard block stones form a built-in compact mixture of the block stones and the soil body, so that the operation waste of replacing and filling the first gravel soil layer and the clay layer is avoided; and the base bearing capacity is effectively improved.
本发明公开了一种山区公路高填方路基谷地软土夹层地基复合处理施工方法，包括如下步骤：施工准备、场地复核、换填耕植土、强夯施工、排水施工、完工验收。在施工过程中，通过将耕植土换填为硬质块石，使置换层成为渗水层，并配合隔水带和盲沟，加速填方路基基底的排水速度；并且，通过强夯施工将第一碎石土层和黏土层进行复合加固处理，排出存储在软土颗粒中及颗粒之间的空隙及水分，提高土层密实度、C值及φ值；同时，通过强夯将硬质块石挤密嵌入第一碎石土层甚至黏土层，不仅将第一碎石土层和黏土层挤密加固，而且使碎石土、黏土和硬块石形成块石和土体的嵌固型密实混合体，避免将第一碎石土层和黏土层换填的作业浪费，有效提高基底承载力。
