Construction method for dynamic compaction replacement in high-sensitivity and seriously liquefied soil layer foundation
The invention discloses a construction method for dynamic compaction replacement in a high-sensitivity and seriously liquefied soil layer foundation, belongs to the technical field of building construction foundation reinforcement treatment, and can solve the problems that high-sensitivity soil and liquefied soil are interlaced and coexist in the same field, conventional dynamic compaction is adopted, and dynamic compaction replacement cannot be constructed. By means of the method, after the side wall of the rammed pit is stabilized, the rammed pit can be gradually pushed downwards and repeatedly reinforced N times to reach the set depth, then backfilling and conventional dynamic compaction replacement construction are carried out, and the problems that in a high-sensitivity and serious liquefied soil site, conventional dynamic compaction replacement cannot form a replacement pier body, liquefaction cannot be eliminated and the like can be solved. The displacement pier body not less than 6 meters can be formed in the field of the type, liquefaction of about 9 meters in a foundation liquefied soil layer is eliminated, differential settlement is reduced, and the bearing capacity of the foundation is improved.
一种高灵敏性+严重液化土层地基中强夯置换的施工方法，属于建筑施工地基加固处理技术领域，可解决高灵敏土和液化土质互层交错、同场并存，采用常规强夯、强夯置换无法施工的状况，每次回填置换料夯2击，使得夯坑侧壁稳固后能逐步往下推进，反复加固N次达到设定深度，然后再进行回填、常规强夯置换施工，可解决在高灵敏性+严重液化土场地中，常规强夯置换无法形成置换墩体、消除液化等问题，通过使用本发明方法，可在此类型场地中形成不少于6米的置换墩体，并消除地基液化土层中9米左右的液化性，减小不均匀沉降，提高了地基的承载力。
