实际工程中,影响锚索极限承载力的因素众多,由于设计计算方法不成熟、施工工艺不够先进等原因,导致理论锚固力与工程实测锚固力存在差异。通过对实际工程中拉力型锚索极限拉拔试验得到的拉力-位移关系的分析,得出在试验土体条件下的锚固长度与有效因子的关系曲线。提出了工程实际中影响锚固力的因素。 In practical engineering, there are many factors affecting the ultimate bearing capacity of the anchor. Due to the immature design and calculation methods, the construction technology is not advanced enough and so on, resulting in the difference between the theoretical anchoring force and the measured anchoring force. Through the analysis of the tension-displacement relationship of the pull-type anchor cable in the actual project, the relationship between the anchor length and the effective factor under the condition of the test soil is obtained. The factors that affect the anchoring force are put forward in engineering practice.
