THE WAYS AND METHODS FOR IMPROVING THE PULL-OUT BEARING CAPACITIES OF GROUND ANCHORS AND REINFORCEMENT EFFECT

Cheng Liangkui Fan Jinglun Zhang Peiwen Zhou Jianming,

摘要: 针对普通预应力锚杆单锚承载力较低的状况,采用理论分析、现场试验和工程应用调查等方法,介绍了荷载分散、后高压注浆和端部扩大头三种能显著提高抗拔承载力的锚杆形式,论述这三种方法各自不同的承载机理、技术内涵、工作特性、实施要领及适用条件,并通过工程实测反映了其锚固效果。

Abstract: Aiming at the state of lower pullout bearing capacity for normal prestressed anchor，three typical kinds of anchorload-dispersive anchor，post high pressure grouting and under-reamed ground anchor，were discussed by adopting theoretical analysis，field test and investigation． The bearing mechanism，the technical connotation，work characteristic，implementation essentials and application conditions of the three ones were discussed，the anchorage effects were also reflected by several measurements in situ．

- post high pressure grouting /
- load-dispersive /
- under-reamed
