摘要： 随着我国铁路建设的高速发展，铁路隧道施工是铁路建设的重要组成部分，随着施工技术的不断进步和设备材料种类的逐渐丰富，人们利用光面爆破技术来在岩层中掘进，这种方法不仅保证了破岩的效率，并且对隧道喷锚、衬砌标准化作业有着重大的作用，本文结合光面爆破的原理和技术要点，对光面爆破技术在隧道掘进施工中的应用和经济性进行分析。
Abstract: With the rapid development of railway construction in China, railway tunnel construction is an important part of railway construction. With the continuous progress of construction technology and the gradual enrichment of types of equipment and materials, people use smooth blasting technology to excavate in rock formations. This method not only ensures the efficiency of rock breaking, but also plays an important role in the standardization of tunnel shotcrete and lining. This paper combines the principles and technical points of smooth blasting to discuss the application and economical efficiency of smooth blasting technology in tunnel excavation construction.
