摘要
长深高速公路(G25)K3457+744～+3458+144段(原梅河高速公路K140+400～+800)左侧边坡的锚索结构利用"锚固结构工后长期性能安全检测评估技术"检测发现预应力损失过大,当前锚索结构的工作性能已经远低于原设计要求的预应力状态。为此通过应力补偿技术对存在上述问题的锚索结构进行预应力补偿加固,使其恢复到原设计水平,确保边坡长期的整体稳定性,期望对类似工程有借鉴意义。
As too much prestressing losing of the anchorage structure at left side slope between K3457 ＋ 744 and K3458 ＋ 144 of Changshen Expressway （G25） has been detected by utilizing ＂long term safety evaluation technique of anchorage structure after construction＂, and the working performance of anchorage structure has been far below the required design prestressing conditions, all of the defects mentioned above have been treated by applying prestressing force compensation technology to resume to design level, so the overall stability of the slope can be assured, which has been expected to provide references for similar engineering projects.
