Finally we set up three - dimensional space model to simulate the space effect during tunnel construction , analyze the transaction between the left runnel and the right tunnel , and also analyze the deformation and stability of mid - partition 最后建立了三維空間模型,對(duì)連拱隧道開挖時(shí)的空間效應(yīng)、左右洞的相互影響,以及中隔墻的變形和穩(wěn)定性進(jìn)行了模擬分析。
