Construction method for reducing post-construction settlement of collapsible loess high fill subgrade
The invention discloses a construction method for reducing post-construction settlement of a collapsible loess high-fill subgrade, and relates to the technical field of subgrade construction. The construction method for reducing post-construction settlement of the collapsible loess high fill subgrade comprises the following steps: S1, after the subgrade backfilling thickness reaches the effectivereinforcing depth of a dynamic compactor, the dynamic compactor is used for conducting reinforcing treatment on a first-layer ramming face, earthwork continues to be backfilled after reinforcing treatment is completed, and when the backfilling thickness reaches the effective processing depth of the dynamic compactor again, the dynamic compactor is used for conducting reinforcing treatment on a second-layer ramming face. The construction method for reducing post-construction settlement of the collapsible loess high fill subgrade uses the dynamic compactor to tamp and reinforce according to thearranged tamping points, leveling and rolling are conducted on the second tamping points after second tamping is completed, backfill is started again after construction is completed, and dynamic compaction is adopted for reinforcing backfill soil, so the effect is remarkable, and post-construction settlement of the high-fill subgrade with collapsible loess as filler can be greatly reduced.
本发明公开了一种减少湿陷性黄土高填方路基工后沉降的施工方法，涉及路基施工技术领域。该减少湿陷性黄土高填方路基工后沉降的施工方法，包括如下步骤：S1、路基回填厚度达到强夯机有效加固深度后利用强夯机对第一层夯击面进行加固处理，加固处理完成以后继续回填土方，当回填厚度再次达到强夯机有效处理深度时，利用强夯机对第二层夯击面进行加固处理。该减少湿陷性黄土高填方路基工后沉降的施工方法，利用强夯机按照布置的夯点进行夯击加固，待第二遍夯击全部完成后对第二遍夯点进行整平碾压，施工结束后重新开始回填，采取强夯对回填土进行补强，效果显著，可大幅减少以湿陷性黄土为填料的高填方路基工后沉降。
