Abstract  

The tunnellining generally consists of tens of thousands of segment rings. In order to reduce the energy consumption of segment erecting process, an energy-saving technology was proposed based on erecting parameters optimization. Taking a Ф3.2 m test shield tunneling machine as the research subject, the mathematical models of doing work and energy distribution during its segment erector finished the positioning work of segments at different positions were built up based on motion and force analysis of each degree of freedom. When energy consumption and appointed position were treated as the optimization objective and constraint respectively, the erecting parameters determination method and selecting principle were obtained by means of solving the problem of energy consumption optimization. The energy consumed during the segment positioning process with three different sets of erecting parameters were calculated, and the calculating result indicated that 4% energy could be saved when the energysaving method was employed. Taking the whole tunnel lining into consideration, the energy saving effect will be more pronounced.

基于拼装参数优化的盾构机管片拼装节能技术

地铁隧道通常由成千上万的环管片拼接而成,为减少盾构机在管片拼装过程中的能量消耗,提出基于运动参数优化的管片拼装节能技术.以Ф3.2 m试验盾构为研究对象,在分析管片定位时管片拼装机构各自由度运动与受力状况的基础上,建立管片拼装机在完成同一环不同位置管片的定位工作过程中系统做功与能量分布的数学模型,通过解决以消耗能量为目标函数、管片目标位置为约束条件的优化问题,得到在实现最小能量消耗的拼装过程中各执行器运动参数确定原则与求解方法.通过对比计算3种不同拼装路径下拼装机消耗能量情况表明,使用参数优化选择方法确定的拼装路径最高可达到4%的节能效果,在实际隧道掘进中累计节能效果将更加明显.
