沪昆线电气化铁路自2006年开通营运以来,部分路堑重力式挡土墙由于诸多原因造成失稳状态,危及行车安全。2012年沪昆线K429重力式挡土墙失稳位移病害发现后,通过对该病害原因的分析和整治方法的实施,找到了对重力式挡土墙的检测和计算方法,并且采取了一些有效整治方案,为当年全路重力式挡土墙的安全评估和整治提供了经验。
Since the electrification railway of Shanghai-Kunming Railway opened its operation in 2006, some gravel retaining walls have become unstable due to many reasons, endangering traffic safety. After the discovery of the instability displacement of the K429 gravity retaining wall on the Shanghai-Kunming Line in 2012, the method of detecting and calculating the gravity retaining wall was found through the analysis of the cause of the disease and the implementation of the remediation method, and some effective measures Remediation program for the gravitational retaining wall of the year all the way to assess the safety and provide experience.
