宝成铁路三滩村崩塌体整治设计

Research and Design of Santan Village rockfall in Baoji-Chengdu Railway

宝成铁路下行线三滩村崩塌体严重影响着宝成铁路的运营安全,地质条件复杂,本文以该崩塌坡体为研究对象,在分析崩塌体特征及其稳定性的基础上,针对崩塌体规模大,地质条件复杂,整体稳定性差,严重影响既有铁路运营安全的特点,本着安全经济的原则,采用设置桩板墙、锚索框架梁、被动防护网等组合式支挡结构及对山体裂缝灌浆回填处理的综合整治措施对崩塌体进行防护和加固,有效地治理了地质灾害,确保了铁路的运营安全。

Santan village rockfall which is located in the Baoji-Chengdu railway line seriously affects the safety of the railway operation. Based on the analysis of its characteristics and stability, it shows that the rockfall body has many character-istics, such as large scale, complex geological conditions, the poor overall - stability, serious impact on the existing railway operation and so on. Therefore, according to the spirit of safety economic principles, this paper takes the rockfall of slope as the research object, and take the comprehensive control measures which includes the sheet pile retaining wall, the anchor frame beam, the passive protective net, and the combination of retai-ning structures to protect and reinforce the rockfall body. The results show that these measures are effective to prevent the geo-logical disasters and ensure the safe operation of the railway.
