大断面岩溶地铁隧道防水施工技术研究

Research of waterproofing technology for double lining subway tunnel

防水工程的好坏是隧道工程质量的重要考核指标,亦对隧道的安全性能起着至关重要的决定。通过对徐州某地铁大断面岩溶隧道防水体系施工工艺及技术的研究,着重介绍各道防水防线施工的工序及控制要点,希望为今后的类似工程提供积累经验。

Waterproof engineering is an important assessment of the quality of tunnel engineering indicators, but also the safety of the tunnel plays a vital decision. In this paper, through the study of construction technology and technology of waterproofing system of large section karst tunnel in Xuzhou, the process and control points of waterproofing line construction are emphasized, and it is hoped that it will provide accumulated experi-ence for similar projects in the future.
