短期填海造陆地质条件下夯填挤淤置换施工技术
|
摘要
人工岛短期填海区地质因回填时间短、土质稳定性差,造成地基承载力低、地基不均匀沉降严重,对原海相淤泥的处理是此类地质区地基处理的关键;通过青岛东方影都酒店群工程的施工实例,阐述了夯填挤淤置换施工新技术的工艺原理、施工工艺及控制要点等,该技术的成功研究与应用,为今后类似工程的设计、施工和业主决策提供了经验和借鉴依据。
For the short backfill time and poor stability of soil in the short-term reclamation geological island,the poor bearing capacity of foundation and uneven settlement is caused. On the original marine,sludge treatment is the key factor of such geological area foundation treatment. Through the construction engineering of Qingdao oriental hotel group, the process principle and control points of dynamic compaction backfilling replacement silt construction technology are described. The success of the technology research and application provides an experience and reference for the decision-making owners for the future similar project design and construction.
