【摘要】 岩土锚固在我国边坡、隧道、地下洞室、基坑、坝体及抗倾、抗浮等工程建设中已得到广泛应用,成效显著。围绕岩土锚固的应用领域与规模、标准化建设、锚固效应与力学作用,荷载传递机制与荷载分散型锚杆(索)、重复灌浆技术、中空注浆锚杆与扩体型锚杆、土钉与复合土钉加固和钻孔机具与监测、检测技术等方面,较全面地论述了我国岩土锚固的主要研究成果和最新进展,并对岩土锚杆的设计、类型及其适应性、腐蚀与防护、长期工作性能与安全评价以及研究方向等有关发展我国岩土锚固的几个关键问题提出了意见。更多还原

【Abstract】 The ground anchorage technology has been widely used in slopes,foundation pits,mines,tunnels,underground caverns,dams,resistance to overturning and floatations,etc.in China with remarkable success.It is expounded more comprehensively that major achievements and the latest progresses in ground anchorage from the application field and scale,standardized construction,reinforcing mechanical effect,load transfer mechanism as well as load-dispersed anchors(cables),repeated grouting technique,hollow-grouted anchor and underreamed anchor,soil nail and composite soil nail,drilling machines and monitor techniques,etc.in China.Meanwhile,some opinions are proposed on several key problems,concerning the development of ground anchorage in China,such as the design,type and adaptability,corrosion and protection,long-term working behavior and safety evaluation,as well as the research direction,etc.of the ground anchors.更多还原
