Abstract The construction quality and efficiency of waterproofing process directly affect the project progress in tunnel construction. However, there are many problems in the waterproof laying trolley, such as high labor intensity, low laying efficiency, poor safety, and so on. Therefore, a multi-functional waterproof laying trolley equipment and its hydraulic control system were designed to solve the problems mentioned above. First of all, the overall mechanical structure of the equipment was introduced, which contained gantry support mechanism, moving mechanism, hoisting mechanism, crawler and synchronous mechanism, scaling platform and support mechanism, and so on. Then, parameters of hydraulic system and hydraulic components were analyzed and selected on the basis of analyzing the working requirement and working principle of the hydraulic system, and the optimal scheme was confirmed. Meanwhile, according to the characteristics of the parallel loop of the hydraulic system, the hydraulic simulation model of lifting loop was established based on AMESim for dynamic simulation analysis and the response characteristic curves such as work pressure, flow and displacement of hydraulic cylinder were obtained. The experimental results showed that the hydraulic system had the advantages of reasonable design, fast response speed, stable performance, high reliability and could meet the work requirements. The research result provides guidance for the optimization design of the hydraulic system of laying trolley.

隧道施工多功能铺设台车液压系统设计及其响应特征分析
在隧道施工中，防水工序的施工质量及效率直接影响着工程进度。针对采用传统的脚手架人工棍棒托顶铺设防水材料存在劳动强度大、铺设效率低、安全稳定性差等问题，设计了一款多功能铺设台车及其液压控制系统。首先，介绍了台车的总体结构，它由门架支撑机构、行走机构、卷扬机构、爬行小车及同步机构、伸缩平台及顶撑机构等部分组成；然后，在分析液压系统的工作要求及工作原理的基础上，对液压系统的参数及液压元件进行了分析计算和选型，确定了最优方案；随后，根据液压系统并联回路的特征，重点针对整升回路采用AMESim软件建立了液压仿真模型进行动态仿真分析，得到液压缸工作时的压力、流量、位移等响应特性曲线。实验结果表明液压系统设计合理、响应速度快、性能稳定、可靠性高，可满足工作要求。研究结果可为铺设台车液压系统的优化设计提供指导。
