摘要
针对太岳山隧道施工过程出现的顶部岩层掉块垮塌、台阶法步长不协调以及台阶高度与格栅钢架高度不匹配等工程问题,提出了施工优化方案,并采用数值计算方法对优化前后的施工方案进行了模拟分析,计算表明:优化后的施工方案有效地保证了隧道的施工质量和施工进度。
In light of Taiyueshan tunnel construction problems including top rock collapse,incoordination benching tunneling method,and mismatching of benching height and grid height,the paper puts forward construction optimizing scheme,simulates and analyzes construction scheme before and after optimization with numerical calculation method. Results show that： optimized construction scheme effectively guarantees the tunnel construction quality and construction schedule.
