一种大型岩石三轴应力摸拟实验装置方案设计

The Design of Large Analogy Unit in Testing Tri-axis Stress on Rock

大型岩石三轴应力模拟实验装置是一种对地下深层岩石的力学性能进行模拟实验研究的必要装备，目前市场上尚无此大型实验设备的产品，本文就该设备的方案设计进行了论证，提出了一种新颖的设计方案。

The large analogy unit in testing tri-axis stress on rock is an essential equipment thatcan be used to have an analog study on the mechanical characteristics of the rock in deep underground. So far there have been no such units on sale in market. Through the discussionof both the necessity and possibility on the unit, the paper offers a much newer, simpler andmore economical approach to the design of the unit.
