摘 要：随着城市化进程的不断发展，城市综合管廊作为重要的基础保障设施，直接关乎着人类的生产和生活。相对于国外，我国在城市综合管廊项目的建设上起步较晚，与发达国家具有一定差距，但是由于我国在此方面投入较大，城市综合管廊有了一定突破，在城市中能够发挥重要的作用。综合管廊防渗最为首要任务，提高其防渗效果能够保障综合管廊稳定、安全运行。于是文章对综合管廊项防渗技术进行探讨，首先对城市综合管廊特点进行分析，然后分析综合管廊渗漏原因，最后分析四个方面的防渗技术，通过这些技术的使用，很大程度上能够提高综合管廊的防渗效果，希望能给相关人员提高参考和借鉴。

Abstract：With the continuous development of urbanization， urban utility tunnel， as an important basic security facility， is directly related to human production and life. Compared with foreign countries， China started late in the construction of urban utility tunnel projects. Thus there is a certain gap with developed countries. However， due to Chinese large investment in this aspect， the urban utility tunnel has made a certain breakthrough， which can play an important role in the city. The anti-seepage of utility tunnel is the most important task. Improving its anti-seepage effect can ensure the stable and safe operation of utility tunnel. Therefore， it is necessary to discusses the anti-seepage technology of utility tunnel. First of all， the characteristics of the urban utility tunnel are analyzed. Then， the causes of leakage are analyzed. Finally， the anti-seepage technology in four aspects is analyzed. Through the use of these technologies， the anti-seepage effect of the utility tunnel can be improved to a large extent， which hopes that it can provide reference for relevant personnel.

Key words：city; utility tunnel; anti-seepage technology

随着城市化进程的不断发展，发布一系列法律法规，提倡城市基础建设，尤其是城市综合管廊的建设[1]。可见城市综合管廊在社会中的重要性。城市综合管廊作为城市地下基础设施，主要由钢筋混凝土构成地下空间，通过将各种工程管线安装到地下空间中，能够节约地上的使用面积[2]。在城市综合管廊项目的建设中，日本在此方面发展速度较快，属于世界上综合管廊建设非常先进的国家之一[3]。随着综合管廊优势的不断突出，我国也逐渐重视综合管廊，不断对其进行推广建设。由于我国在城市综合管廊建设上的起步较晚，但近年来，我国对其进行了大量研究和实践，已经有了不小的突破[4-5]。……
