| 摘 要： | 本文对可用于测试和监测岩体应力及其变化的光学传感器进行了系统地研究，推导出利用传感器上产生的干涉条纹确定岩体应力的普遍计算式，提出用“灰度法”进行小数级条纹补偿，为施工现场岩体应力的测试和监测提供了一种简单可行的方法。

| Abstract: | An optical sensor for test and monitor of rock stresses is studied systematically.A general algorithm is derived to determine rock stresses on the basis of interference fringes of optical sensor. A gray scale compensation technique is presented to determine fractional fringe orders. As a result, a simple and effective approach is made available for test and monitor of rock stresses in situ. |
