摘要
根据局部变形地基梁法,利用改进了的压力拱理论计算地层压力,对212国道某一隧道衬砌(变截面直墙拱)进行了内力计算,同时利用大型有限元进行模拟,分析了拱形结构的受力特点,对隧道工程的设计与施工都具有一定的指导作用。
According to partial deformed basement beam method, improved pressure arch theory are used in calculating the pressure of basement, inside force of a tunnel along national road 212 is also calculated, meantime, simulates by large limited unit, analyzes the forcing features of arch structure, has guiding effect for designing and construction of tunnel project.
