摘　　要：针对岩体破碎作业过程中产生振动、环境污染、安全等技术难题,研究开发新型破岩装置。设计制作以TiNi形状记忆合金管为压力元件的形状记忆破岩装置,阐明了形状记忆破岩装置的工作原理,并对其破裂力进行力学分析和室内混凝土破裂实验验证。结果表明:该破岩装置具有很强的破裂力,破岩速度快,可以实现对混凝土的破裂。According to many technical problems in the process of rock breaking, such as blasting vibration, environmental pollution and safety, a new rock breaker was studied and developed. The rock breaker was produced with TiNi shape memory alloy（SMA） pipes as pressure elements, and the principle was illustrated, including the mechanics analysis and the indoor experiments of concrete rupture. Results show that the rock breaker works steady and quickly with strong strength, which can be used to break concrete efficiently.
