接近區段長度-
In order to achieve the optimized tunneling approach, first, tunneling procedures, shift length, horizontal jet grouting length, bench length and space length between c and d part of crd method are optimized ; on the basis of these results, two kinds of tunneling schemes are calculated with three - dimensional fem and the optimized tunneling scheme is achieved. as results of the optimized scheme, the conclusion is made that the gas pipe above the tunnel of sk3 + 355 section is secure. the calculation results are verified through comparison of numerical simulation results and site - monitoring measurement data
為得出適合本段工程的最佳施工路線,利用大型有限元通用軟體ansys對開挖順序、開挖進尺、水平旋噴長度、臺階長度及crd工法施工的c 、 d部相錯長度進行了有限元數值模擬和優化分析,並利用這些分析結果,進行了兩個施工方案的三維有限元動態施工模擬,得出了較優的施工方案,並利用施工后的地表沉降槽曲線,對sk3 + 355斷面處隧道上方的煤氣管線的安全性進行了分析,得出了利用此施工方案施工不會造成此處煤氣管線破壞的結論。 -
