摘　　要：中国地下岩土工程开发常面临高地应力、地下岩溶和极软岩等复杂地质条件,造成岩体结构松散断裂,快速、准确且方便地获取岩体力学参数对于地下岩土工程建设至关重要。自主研制了一台自动和连续监测岩石钻进过程的XCY-2旋切触探系统,包括动力钻进控制系统、全伺服系统、智能监测系统等多个系统,安装流程简易且试验操作步骤简单。基于该系统开展了完整岩层、分层岩体等不同条件下的岩体旋切触探试验,探究旋切钻进过程中随钻参数与不同岩性的特征响应关系,研究结果表明:(1)智能监测系统能够有效地智能控制和实时监测钻进速度、动力头转速、钻进扭矩、水压力、钻进压力和钻进深度等钻进参数,实现了地下工程施工高精准的钻进操作和监测;(2)钻进不同岩层组合试块时钻进压力和钻进扭矩会产生波动,上下差距明显,而钻速和转速在整体试验过程中保持稳定输出,证明了钻进过程中钻进参数的监测结果可靠。(3)钻进扭矩和钻进压力在不同岩层交界处有明显波动现象,对不同岩性的岩石实时感知明显,实现了岩层界面的准确定位。XCY-2旋切触探系统为地下岩体物理力学性质测试提供了新的途径。China's underground geotechnical engineering often faces complex geological conditions,such as high in-situ stress,subterranean karst,and extremely soft rock.These conditions can lead to loose and fractured rock structures,making it crucial for underground geotechnical engineering construction to quickly,accurately,and conveniently obtain rock mechanics parameters.We have autonomously developed the XCY-2 rotary cutting and penetrating system,a device for continuous monitoring of the drilling process.Various systems are integrated into this device,such as a power drilling control system,a comprehensive servo system,and an intelligent monitoring system.The installation process is straightforward,and the testing procedures are simple,facilitated by a human-computer interaction interface.To investigate the relationship between drilling parameters and the characteristic responses of different rock types during the rotary drilling process,we conducted comprehensive rotary drilling penetration tests under various conditions,including intact rock layers and layered rock masses,using the device and procedure.The test results showed that:1)The intelligent monitoring system efficiently controls and monitors drilling parameters in real-time,including drilling speed,rotation speed,drilling torque,water pressure,drilling duration,drilling pressure,and drilling depth.This technology significantly facilitates high-precision drilling operations and continuous monitoring during underground construction.2)When drilling through rock samples of various strength grades,we observed real-time fluctuations in drilling pressure and torque,while the drilling speed and rotation speed remained stable throughout the testing process.3)Significant fluctuations in drilling torque and pressure were observed at the interfaces between different rock layers,indicating real-time perception of different rock types and achieving accurate positioning of rock layer interfaces.The XCY-2 rotary cutting and penetrating system provides a new approach for tes
