摘要
通过阐述DCM桩施工原理,分析香港国际机场第三跑道填海工程海堤基础DCM处理后海床面的隆起情况,通过分析海床的隆起对海堤护面块石、压脚块石、整体岸坡稳定的影响,得到香港三跑工程护面和压脚块石重量不能满足稳定设计要求,而整体稳定虽受到影响但是该项目仍能满足设计要求的结论,并给出了建议的处理方法。
By expounding the construction principle of DCM piles,this paper analyzes the heave of the seabed surface after DCM treatment of the seawall foundation in the main reclamation works of Hong Kong International Airport three runway system project.By analyzing the influence of the seabed heave on the stability of armor rock,toe rock,and overall bank slope of seawall,it is concluded that the weight of armor and toe rocks in Hong Kong three runway project cannot meet the stability design requirements,although the overall stability is affected,the project can still meet the design requirements,and the proposed treatment methods are given.
