【摘要】 为满足全断面岩石隧道掘进机（TBM）在研发与施工中对破岩机理、掘进效能及刀具磨损特性等研究的试验需求，将刀盘进行模块化设计，研制出一套集滚刀回转破岩、刀盘连续掘进、滚刀磨损测试和掌子面图像重构为一体的TBM多功能缩尺破岩试验平台。该试验平台尺寸为1 180 mm×960 mm×1 600 mm，可容纳最大岩石尺寸为540 mm×540 mm×120 mm，推力最大量程为200 k N，扭矩最大量程为2 000 N·m。试验平台建成后，通过更换刀盘刀具，进行滚刀破岩试验、滚刀群掘进试验、滚刀磨损试验及掌子面围岩重构试验等系列试验，取得了理想的试验效果和可靠的试验数据，验证了试验平台功能的全面性和可靠性。更多还原

【Abstract】 To meet the experimental requirements for studying rock-breaking mechanisms, excavation performance,and cutter wear characteristics during the research and construction of full-face TBM, an innovative modular cutterhead design was proposed, and a scaled-down multifunctional TBM rock-breaking test platform was developed. The platform integrates disc cutter rotary rock-breaking, continuous cutterhead excavation, disc cutter wear testing, and tunnel face image reconstruction. The dimensions of the test platform are 1,180 mm × 960 mm × 1,600 mm, accommodating rock specimens up to 540 mm × 540 mm × 120 mm in size. The maximum thrust capacity is 200 kN, and the maximum torque capacity is 2,000 N·m. After construction of the test platform, a series of experiments were conducted by replacing the cutterhead cutting tools, including disc cutter rock-breaking tests, disc cutter group excavation tests, disc cutter wear tests, and tunnel face surrounding rock reconstruction tests. The results demonstrated desirable experimental outcomes and reliable test data, verifying the comprehensiveness and reliability of the test platform’s functions.更多还原
