三轴应变是指变形前后，应变椭球体中三个主应变轴长度都改变的应变状态。
此外还介绍了用两种三轴应变计进行岩体应力测量的结果以及能考虑自重边界元法的实际应用。
Results of measurements on rock mass stresses by two kinds of triaxial strain cells are reported. Finally the possible applications of BEM with gravity are discussed.
因此，本文从研制高精度中型动三轴仪入手，采用微小应变测试技术，以实现这一目标。
In this thesis, the medium scale dynamic triaxial apparatus, with micro strain measure technique, is developed to realize the aim.
