Intelligent Construction of Shield Tunnels Based on Resilience Theory

  • 摘要: 以盾构隧道为主的城市轨道交通在“十三五”期间已取得了跨越式的进步,盾构掘进设备在智能化方面取得了飞速发展,但隧道结构设计、结构制造和现场管片拼装的智能化方面,仍需要大的创新与突破。面对建设韧性智慧城市的战略目标,盾构隧道还存在系列问题亟需解决,如对于新材料的物性认识浅、理论少;传感的布置缺乏针对性,监测感知差;隧道管片拼装大量依靠人工,误差大。解决这些问题的关键在于构建一个基于韧性理论的智能化盾构隧道建造系统,通过利用材料和结构的韧性特点,结合计算机等信息技术,采用韧性设计、智能感知、智能制造、智能拼装等一系列措施,使得隧道结构中的材料可智能感知、结构可精准监测、数据可实时孪生、信息可高效管理、制造可自动操控、过程可全域感知、模型可动态调节、管片可智能拼装,最终实现韧性城市的盾构隧道智能化建设。

     

    Abstract: Urban rail transit that is mainly based on shield tunnels has made rapid development during the period of the 13th Five-Year Plan, and shield tunnelling equipment has obtained fast progress in intelligent development.However, the tunnel structure design, structural element production and on-site segment assembly needs more innovations and breakthroughs in terms of intelligence. Faced with the strategic goal of building a resilient smart city, we also still have a series of problems needing urgent resolutions for shield tunnelling, such as limited knowledge and theory about the physical properties of new materials, the lack of target in the arrangement of sensors and poor monitoring perception, and the heavy reliance of tunnel segment assembly on manual labor, which produces large errors.The key to solving these problems lies in building an intelligent shield tunnel construction system based on the resilience theory. By using the resilience characteristics of materials and structures, and in combination with computer and other information technologies, a series of measures could be taken such as resilient design, intelligent percep? tion, intelligent production, and intelligent assembly, etc. to make the materials in tunnel structures intelligently perceivable, the structure accurately monitorable, the data twinned in real time, the information efficiently manageable,the production automatically manipulable, the process perceivable in ganzfeld, the model dynamically adjustable, and the segments intelligently assembled, thus finally achieving the goal of construction of shield tunnels in a resilient city
