盾构施工人工测量与自动测量技术探讨

摘要

介绍了上海市轨道交通12号线顾戴路-东兰路区间φ6.34 m土压平衡盾构在2.1 km的掘进的过程中，为确保隧道顺利贯通，指导盾构沿设计轴线推进，所采用的人工测量与自动测量的方法及原理。在国内盾构法施工中，盾构机的导向既有人工测量方法，也有自动导向方法。具体施工过程中两套测量系统、相互校核，不断修正，主要相互验证测量数据计算的准确性和测量仪器的误差。%This paper introduces the No .12 line in Shanghai Gu Dai Road -East Portland Road range φ6.34m earth pressure balance shield 2.1km tunneling process ,to ensure that the tunnel was bored through ,guidance shield along the design axis to promote the use ofmanual measurement with automatic measurement methods and principles .
