沉管隧道基础处理方法研究分析
|
摘要
为了给沉管隧道基础处理方法的选择提供相应的参考信息,文章调研了国内外沉管隧道基础施工技术和应用效果,并结合基础处理的方法和特点,从技术、经济、风险、工期等方面综合研究分析了沉管隧道采用先铺法和后铺法进行基础处理的优缺点。通过深入分析研究国内外工程实例,针对相应的施工环境和沉管结构等指标,提出了不同地质和工况等条件下选取基础处理方法的原则,并进一步提出了清淤装备开发的必要性。研究结果对沉管隧道工程设计与施工具有一定的借鉴意义。
In order to provide reference information for the selection of foundation treatment methods of the immersed tunnel,the construction methods and effects of the immersed tunnel foundation at home and abroad were studied,the advantages and disadvantages of the pre-bedding and post-bedding methods were analyzed in terms of technology,economy,risk,construction period and other aspects based on the characteristics of foundation treatment.The principles of treatment methods for the foundation under different geological and working conditions were proposed in view of the construction environment and structure of immersed tube based on a thorough analysis of engineering cases at home and abroad,and the necessity of developing the dredging equipment was put forward.
