提出能够完善和提升现有工程岩体质量评价方法的一套新技术、新方法和新规律。新技术为现场钻孔过程监测(DPM)技术。新方法为钻孔过程时空数据的快速直观时间序列分析方法。新规律为钻头进深随时间曲线呈分段线性变化,每段钻进速度是常数,每一常数钻速段代表一个均匀抗钻岩石(岩块),常数钻速之间的突变点或低钻速段分别为钻孔穿过岩块间断面的截点或截段。DPM可以提供工程岩体质量评价完善和提升所需要的新的测量方法和数据,从而可以快速、有效、定量地测量到岩石块体的单轴抗压强度、大小和地下分布,以及岩石块体之间界面断面的产状、延伸、凸凹起伏平整度、厚度和充填物质的物理和力学性质。通过实例来介绍、分析和解释这套技术、方法和规律。并且给出DPM钻孔过程监测完善和提升现有工程岩体质量评价RQD,Q,RMR和BQ方法的具体途径和计算公式,能更客观全面地确定岩块单轴抗压强度、岩体质量指标、岩体完整程度、岩石坚硬程度和间断面。
Put forward a set of new technologies, new methods and new rules that can improve and improve the existing engineering rock mass quality evaluation methods. The new technology for on-site drilling process monitoring (DPM) technology. The new method is a fast and intuitive method of time series analysis of spatiotemporal data of drilling process. The new rule is that the depth of penetration of drill bit changes linearly in piecewise with the time curve. Each drilling speed is constant, and each constant drilling rate represents a uniform anti-drilling rock (rock block) Velocity sections are the cut-off points or sections of the borehole through the inter-section of the block, respectively. DPM can provide new measurement methods and data needed for the improvement and enhancement of engineering rock quality assessment so that uniaxial compressive strength, size and subsurface distribution of rock mass can be measured quickly, effectively and quantitatively, as well as rock mass The interfacial section between the appearance, extension, bump roughness, thickness and filling material physical and mechanical properties. Through examples to introduce, analyze and explain the technology, methods and laws. The specific ways and calculation formulas of DPM drilling process monitoring to improve and enhance the existing engineering rock mass quality evaluation RQD, Q, RMR and BQ methods are given. The uniaxial compressive strength, rock mass mass Indicators, integrity of rock mass, rock hardness and discontinuities.
