摘要
城市地下铁道工程为百年工程,其防水工程的特点是防水要求高、材料繁多且工艺复杂。本文以西安地铁二号线工程为背景,调查了全国各地地铁防水材料的选用情况,并重点介绍了西安地铁防水设计和施工的情况。在深入调查分析渗漏水位置、特点和原因的基础上,提出了防水设计和施工中应注意的问题和改进建议。西安地铁必须要面对特殊地质灾害——地裂缝,针对地裂缝的活动性,经过科研设计攻关,研发了一种能够主动适应地裂缝变形的具有大应变特性的新型独特的防水体系,专题讨论了地裂缝防水技术的方案和改进措施建议。本文的研究重在对实际工程的总结,希望能够引起同行们的重视。
The city metro is a century project. Its waterproofing work is characterized by strict requirement, variety of materials and complicated technique. Based on the second line of Xi＇an metro, the waterproofing situation have been investigated and the waterproofing design and construction have been introduced in this paper. Some questions and improvement advice have been put forward on the basis of investigating leakage positions, character and reasons in metro projects. Xi＇ an Metro have to face the special geological disasters-ground fissures. Through scientific research and design, a new unique waterproofing system has been developed to adapt to large strain deformation characteristics for ground fissures. In the mean time, the improved measures have been discussed in this paper. The authors hope that our counterparts can attach importance to this problem.
