一、前言目前,全长粘结的锚杆在地下工程中广泛采用,但它的受力计算至今仍无完善的理论。最早,人们把这种锚杆也作为点锚式锚杆来计算,近年来已有多种理论反映粘结式锚杆的受力机理。然而,这些理论也只在分析单根锚杆受力机理时考虑了粘结式锚杆的受力特点,而 I. INTRODUCTION At present, the full-length bonded anchor rod is widely used in underground engineering, but its force calculation still has no perfect theory. In the earliest days, people used this type of anchor rod as a point-anchored anchor rod. In recent years, various theories have reflected the stress mechanism of cemented anchor bolts. However, these theories only consider the stress characteristics of cemented bolts when analyzing the stress mechanism of a single bolt.
