| 摘 要： | 主动铰接型盾构机在曲线隧道开挖中应用广泛，其盾构姿态的精密解算是盾构机自动导向系统的核心功能，也是盾构掘进中进行盾构机实时纠偏的前提和基础。国内外盾构机自动导向系统提供商对自身盾构姿态计算原理和方法保密的现状，给盾构机姿态人工复核和盾构施工带来了较大困难。本文在研究两款国产盾构机和日本演算工坊棱镜法自动导向系统的基础上，利用立体几何和空间投影变换原理，提出了主动铰接型盾构机姿态精密解算方法，给出详细推导计算公式。通过对多台盾构机在不同隧道线型内多组姿态坐标数据的计算和对比，验证了该盾构姿态精密解算方法的正确性。

| Abstract: | The active articulated shield machine is widely used in curved tunnel excavation. The precise calculation of its shield posture is the core function of the automatic guidance system of the shield machine, and it is also the premise and foundation for the real-time deviation correction of the shield machine in shield construction. The current situation of shield machine automatic guidance system providers at home and abroad keeping their own shield machine positioning calculation principles and methods secret has brought great difficulties to shield machine positioning manual review and shield construction. Based on the study of two domestic shield machines and the prism method automatic guidance system of the Japanese calculus workshop, a precise positioning calculation method for the active articulated shield machine is proposed by using the principles of solid geometry and spatial projection transformation, and the detailed calculation formula is given. Through the calculation and comparison of multiple sets of positioning coordinate data of multiple shield machines in different tunnel lines, the correctness of the precise calculation method of shield posture is verified. |
