盾构选型涉及刀盘开挖系统、主驱动系统、管片拼装系统、螺旋出碴系统等关键系统选型设计,国内地质条件特点不一,盾构选型设计计算比较反复,各系统累计计算量较大,为了提高盾构选型工作的高效性、可靠性,本文基于自主开发的Visual Basic程序计算方法,以西安地铁某标段区间设备选型过程为例对盾构主机各关键系统进行选型设计。
The selection of shield involves the design and selection of key systems such as cutterhead excavation system, main drive system, pipe segment assembly system and screw ballasting system. The domestic geological conditions have different characteristics, the shield design selection is repeated and the sum of each system A large amount of calculation is required. In order to improve the efficiency and reliability of shield selection, based on the self-developed Visual Basic program calculation method, taking the equipment selection process of a certain section of Xi’an Metro as an example, Selection design.
