盾构掘进机及其液压技术的应用

Shield TBM and its applications of hydraulic technology

简要介绍了盾构掘进机及其发展趋势。就液压技术在盾构驱动及控制上的应用提出了可能的途径,如:变转速泵控马达、负载敏感等技术的应用,不仅在节能的同时可望解决长期困扰盾构施工的发热问题。

This paper briefly introduced shield TBM and its development trend. The potential path of hydraulic technique was pro-posed as the power transmission and control system in shield TBM. The application of the variable-speed pump-control-motor and load sensitive control system, for example, can increase the energy efficiency and reduce the thermal value of the system.
