摘要
该文从旁通道(泵站)的功能、设置和优化设计的角度出发,提出两种类型的地铁区间可不设旁通道的方案,建议参考大隧道(黄浦江越江)的成果,来进一步优化地铁旁通道(泵站)的设计。文章运用人工冻结法原理,分析旁通道(泵站)建设的施工、冻融沉降和运营维护风险,建议加强针对冻融沉降规律的试验和研究,提高人工冻结法施工的可靠性和耐久性,并提出了相关建议。
The article puts forward two kinds of schemes that the bypasses can not be constructed in the areas of the metro from the angle of the functions,construction and optimization design of the bypass (pumping station),suggests to refer the achievement of the large tunnel (crossing Huangpu River) further to optimize the design of the metro bypass (pumping station). The article applies the principle of the artificial freezing process,analyzes the risks of the construction,freeze-thaw settlement and operation maintenance in the construction of bypass (pumping station),suggests to strengthen the experiment and study of freezing freeze-thaw settlement rule,enhances the reliability and durability of construction by artificial freezing process,and puts forward the relative suggestions.
