Because of the advantage of Twin Shear Unified Strength Theory,the proposed theory system can be used in many engineering fields,especially for materials with obvious intermediate principal stress effect.

• 由于双剪统一强度理论的通用性和优越性已被逐渐认识；因此；平面应变统一滑移线场理论可以应用于各种工程材料；尤其对在土木工程中广泛应用的、具有强烈中间主应力依赖性的岩土类材料；本理论会更显示出其优越性.
