The infrared remote controller is a cheap, small, simple, reliable and effective product. It can effectively resist electromagnetic interference and ensure safe operation of the system. Using remote technology can reduce manipulative difficulty during soil bin testing and realize single operation of the whole system. Practical application many times demonstrated that the infrared remote controller can work reliably and improve work efficiency considerably.Besides control the movement of tester, the soil bin tester driving control system can adjust the tester speed by rule and line, which was impossible to former test equipments. The range can be adjusted from -1.45m/s to 1.45m/s, the positive and minus sign denotes the direction of tester running.

土槽台车动力控制系统的控制参数均通过人机交互界面输入；系统能够实现对台车行驶速度、位移和时间的实时采集、显示和存储功能，并设有对数据库的操作功能，方便试验人员对数据的查询、修改、删除和保存；试验过程中系统为试验人员提供了台车速度曲线，并能实时动态显示，用来监测台车的运行状况；为了确保试验过程中试验设备和人员的安全，系统增加了控制台车行驶位移和时间的功能；系统使用的防脉冲干扰平均值法处理采集的数据，剔除奇异项，减少了干扰在有用信号中的比重，并能直接显示出所采集数据的均值和方差，节省了处理数据所需的大量时间，提高了工作效率。

In this paper we combining connecting tunnel project of Subway Line 4 at Xidan-lingjing bystreet in Beijing. To aim at the difficulties of building large-span connecting tunnels in the fine sand layer, through roads and underground pipelines, construction nearby buildings and other project difficulties. Using theoretical analysis, numerical simulation, field tests and other research methods to comprehensive and systemic research the stratum deformation mechanism and process control techniques of shallow excavation method, and a series of results were obtained. Firstly, use the stochastic media theory to analyze the stratum deformation mechanism, concretely analyze the analytic equation of surface horizontal displacement and deformation which were caused by the excavation of single-hole and double-hole tunnel, and further discussion on ground settlement, vertical deformation, surface horizontal displacement and horizontal deformation. Analyzing the main influence factors of surface displacement, and combined with practical work to proof the theory which was applied to shallow buried single-hole tunnel in fine sand layer was scientific.

本文结合北京地铁四号线西单～灵境胡同渡线隧道工程，针对在粉细砂地层中修建大跨渡线隧道，下穿道路和地下管线，临近建筑物施工等工程难点，利用理论分析、数值模拟、和现场监测等多种研究手段，对浅埋暗挖隧道地层变位机理及控制技术，深入地进行全面和系统的研究，并取得以下成果：(1)引入随机介质理论，对地层变位机理进行了分析，具体分析了单、双孔隧道开挖引起的地表位移及变形的解析方程，并深入探讨了地表沉降、垂直变形、地表水平位移和水平变形的特点，同时分析了影响地表位移的主要因素，并结合工程实例，佐证该理论应用于粉细砂地层浅埋暗挖单孔地铁隧道的科学性。
