摘　　要：随着经济发展及科技水平的提高,硬岩掘进机、盾构机、反井钻机、巷道掘进机等机械在地下工程施工中得到了空前发展,机械破岩试验成为地下工程施工机械不可或缺的一个试验手段,以指导地下工程施工机械设计和施工。文章介绍了北京工业大学自主研制的机械破岩试验平台,该试验平台的设计制造综合考虑了高地应力、刀盘旋转和多个刀具同时破岩等工况,也考虑到不同破岩机械不同类型刀具破岩试验,还能在岩样箱中考虑到不同的岩体结构,可以真实模拟不同机械刀具的现场施工工况。试验平台由机械系统、液压系统、自动控制系统和数据采集系统组成。试验平台制作完成后,进行了多个不同工况的验证试验,达到了原定的设计要求。With economic development and the improvement of science and technology, such construction machin-ery as rock tunnel boring machines, shield machines, raise boring machines, and road headers have been applied un-precedentedly to underground works. Therefore, the testing of mechanical rock breaking has become an indispens-able experimental means for construction machines used in underground works and can also guide the design andoperation of those machines. This paper introduces a new mechanical rock-breaking testing platform developed byBeijing University of Technology that is designed and manufactured by considering such factors as the influence ofhigh ground stress, cutterhead rotation and rock breaking by multiple cutters at the same time. Meanwhile, other cas-es such as different rock-breaking tools for different excavation machines and different rock mass structures in asample box are taken into account, which makes for a realistic simulation of construction conditions onsite for differ-ent cutting tools. The testing platform consists of a mechanical system, hydraulic system, automatic control systemand data acquisition system. The completed platform has been used for several tests under different cases, and testresults proved that this platform meets its design requirements.
