| 中文摘要: |
| 通过对徐州云龙山东二环路扩建隧道工程k0+126的施工影响,采用有限元施工模拟作了超前预测,从理论上论证了暗挖施工的可能性,保障了邻近建筑的安全.同时对土体支护、支护结构、支护与土体相互作用及施工过程进行模拟,以达到对支护结构变形作出预报的目地.对暗控法施工产生的影响做了超前预测分析,为安全施工提供了指导.针对埋深浅,地质条件复杂的特点,采用有限元法进行模拟分析,为方案的确定提供了可参考的依据. |
| 英文摘要: |
| Through the construction influence of kot126 tunnel reconstruction engineering in Xuzhou Yunlong mountain and the advanced prediction of construction simulation with FEM,embedding construction are possible in theory.The safety of heighouring architectures are protected as well.The soid mass supporting stake,supporting structure,suppurting interaction and the construction process are simulated,the suppurting structure deform are predicted also.Due to the advamced prediction analysis of influence of embedding anstruction,the guides for safely construction are provided。Based on the character of the shallow of enbedded depth,complicate geological condition,and the simulation analysis of FEM,the referrence decision basis of projects are determined。 |
