摘　　要：由于老管廊结构已经运营多年,主体结构在严峻的地下环境作用下,承受了长期侵蚀,产生了各种程度的损伤,已经经不起大幅度的扰动。为选择安全经济高效的新老结构连接方法,依托某综合管廊工程,提出了“钻孔桩+门架结构”的既有管廊保护措施连接方法,通过数值模拟分析,研究了各类结构在不同工况下的变形情况。Because the old pipe gallery structure has been in operation for many years,the main structure has been eroded for a long time under the action of the severe underground environment,resulting in varying degrees of damage,and it is difficult to withstand significant disturbances.In order to select a safe and cost-effective connection method for the old and new structures,relying on the Century Avenue(Xingning Road-Dongming Road)comprehensive pipe gallery project,a kind of"bored pile gantry structure"of the existing pipe gallery protection measures connection method is proposed,and the deformation of various structures under different working conditions is studied through numerical simulation analysis.
