With an analysis of soil liquefaction potential for free field of nanjing metro line 1 under 7 degree earthquake, as well as for excavated field, in line with railway engineering anti - earthquake design specification, dynamic triaxial tests and theoretical analysis using efficient stress method, the author comes to the conclusion that, when metro plate is located at layer s and the layer is thick, liquefied area is at metro bottom plate ; in some local section liquefied area is at metro top plate, or arch sides at the top of metro in most places
摘要採用鐵路工程抗震設計規范、動三軸試驗及有效應力的理論分析相結合的方法,對南京地鐵南北線( 1號線)區間隧道開挖后其地基土在7度地震情況下的土層液化情況進行分析得出:當隧道底板坐落在5層且5層較厚時的液化區出現在隧道襯砌底板處;局部地段液化區出現在隧道頂部及拱腰;大部分地段的液化區出現在隧道頂板上方。Since the shallow depth excavation is the main factor to cause ground settlement in shenzhen subway tunnel, this paper discusses some corresponding countermeasures including the improvement of ground property, appropriate draining of groundwater, scheduled excavation depth and width, etc, to control strata distortion and surface settlement, and argues that these measures are expected to effectively control surface settlement while constructing city subway in soft ground excavation
摘要針對深圳地鐵淺埋暗挖隧道施工中影響地表下降及地層變形的因素,提出了遵循「十八字」原則、改善土體特性、適度排放地下水、根據地層條件選擇施工方法、增大左右線隧道開挖面的距離、合理確定開挖進尺、提高施工效率、加強初期支護、及時施作二次襯砌等對策。It was shown that the maximum displacement occurred on the tunnel axis when one tunnel was excavated, while the maximum value happened near the shallow tunnel and between the area of two tunnels when two adjacent tunnels were excavated at the same time
分析結果表明:單條隧道開挖引起的地表最大沉降值出現在隧道軸線的正上方,而兩左右或上下相鄰隧道開挖的地表及土層內部的最大沉降值則出現在兩隧道的縱軸線之間,且偏向上方埋深較淺的隧道。By face failure and ground subsidence investigation and in - suit monitoring analysis in some lots of shenzhen metro phase line, especially of lot 3a in which two large ground landlides have occurred in construction, the reasons of ground subsidence are expatiated respectively from three aspects, including the characters of the physical mechanical parameters of stratum above tunnel, the monitoring analysis of stratum deformation and contruction technics causation
通過對深圳地鐵期工程土建施工中全線部分暗挖標段出現的工作面失穩、地表塌陷工程實踐和現場監測結果分析,特別著重對連續2次出現地表塌陷的3a標暗挖隧道研究,從隧道上覆地層物理力學性質參數、地層變形監測分析及施工工藝原因3方面闡述了地表塌陷的原因。The change of energy in wall rock is tracked in the whole process and the amount of energy transferred to linings is also evaluated. 5 ) based on the principal of energy invariance and the energy properties of sfrc, a practical design equation that related the thickness of projecting sfrc to the energy related properties of tunnel is given in the end. this equation is then used to design a single - track railway tunnel in iii grade rock condition
並進一步推導了不同形式的構件間的能量耗散關系,為將標準試驗的能量統計結果運用於實際結構中打下了基礎; 4 )利用有限元軟體對隧道開挖過程進行了三維模擬,得到了隧道圍巖在開挖掘進過程中的能量轉化趨勢和規律,得到了鋼纖維噴射混凝土襯砌在支護過程中的能量變化; 5 )利用能量守恆原理和已經推導出的構件能量耗散關系,建立了鋼纖維噴射混凝土襯砌厚度與圍巖開挖能量變化間的關系,並運用此方法對級圍巖條件中的鐵路單線隧道的鋼纖維噴射混凝土襯砌進行了設計計算;分享友人
