摘要：锚杆是目前煤矿、岩土等支护工程中常用的材料,在FLAC^3D中可进行锚杆支护的多角度数值模拟研究,文章对FLAC^3D锚杆支护的数值模拟研究进行总结和展望。分析表明:目前FLAC^3D中建立锚杆模型以Cable、Pile两结构单元较多,可采用Beam、Liner等构建金属钢、托盘、锚喷层等支护要素。FLAC^3D一般作为验证性手段,对实验、实践内容进行证明。重点总结了锚杆及支护构件、预应力锚杆、煤矿巷道支护、岩土工程支护、特殊锚杆的实现等研究进展。当前的研究应用中,存在复杂工程问题的动态还原能力相对较弱、时空与时步不对应、研究细节缺失及二次开发的非公开性、对理论研究的支撑作用相对薄弱等问题。未来,FLAC^3D依然作为重要的模拟手段应用于新型支护理论和支护技术的验证,并可在跨平台建模及跨平台研究、精细化建模与多因素耦合研究等方面取得新的突破。
The bolt is a commonly used material in coal mines,geotechnical and other supporting projects.The multi-angle numerical simulation of rock bolt support can be carried out in FLAC^3D.This paper summarizes and forecasts the bolt support numerical simulation in FLAC^3D.The research shows that cable and pile structure element are used frequently in current rock bolt model in FLAC^3D,and beam,liner can be used to build elements such as metal steel,tray and anchor spray layer.FLAC^3D is generally used as a verification tool to prove the truth of experimental and practical content.The research progress of bolts and supporting elements,pre-tensioned anchors,coal mine roadway support,geotechnical engineering support and modeling of special bolts are summarized.In the current research applications,there are problems such as relatively weak dynamic restoration of complex engineering problems,non-correspondence between real time and steps in FLAC^3D,lack of research details and non-disclosure of secondary application,and relatively weak support for theoretical research.In the future,FLAC^3D still can be used as an important simulation method for the verification of new support theory and technology,and can make new breakthroughs in cross-platform modeling and cross-platform research,and refined modeling and multi-factor coupling research.
