摘　　要：本文介绍了变弹模成层岩基受预锚荷载作用的三维光弹性实验过程。求出了岩基在锚固应力作用下锚根附近的应力场,并和电测成果、理论计算成果进行了比较,结果非常相近.为进一步探讨这些问题提供了可靠的依据.In this paper,a three-dimensional photoelastic experiment is introduced for stud- ing layered rock under the load of prestressing anchor.The experimentally obtained stress field in the rock near the root of the anchor is well agreed with the results of electometric test and theoretical analysis.The experiment and its results provide a basis for further reseach.
