摘要
以杏子山隧道为背景,围绕其仰拱施工中所涉及到的顶模以及栈桥技术展开分析,对仰拱(填充、底板)施工进行详细的探讨,从而有效控制了混凝土的坍落现象,提升了混凝土的可成型性。
Based on the background of Xingzishan tunnel, the top mold and trestle technology involved in the invert construction were analyzed, and the invert(filling and floor) construction was discussed in detail, so as to effectively control the landslide of concrete and improve the formability of concrete.
