Analysis of Over-square Causes and Control Measures of Wet Sshotcrete in Tunnel
-
摘要: 本文结合成昆铁路峨眉至米易段 EMZQ-3 标老鼻山隧道工程实例，阐述了老鼻山隧道湿喷混凝土超方原因，并针对原因制定了控制措施，以及产生的经济效益和社会效益，为降低隧道施工成本提供了可行性方案，对今后隧道湿喷混凝土超方控制具有一定借鉴意义。Abstract: Taking the EMZQ-3 bid Laobishan tunnel project from Emei to Miyi section in Chengdu–Kunming Railway as an example, this paper expounds the causes of over-prescription of wet shotcrete in Laobishan tunnel, and formulates the control measures according to the causes, as well as the economic and social benefits, it provides a feasible scheme for reducing the cost of tunnel construction, and has certain reference significance for the over-square control of wet shotcrete in the future.
