| 摘 要： | 成渝客运专线响滩子双线大桥上跨既有成渝铁路,不可避免地需要开挖既有路堑边坡,但路堑边坡分布大量危岩落石,工程有安全风险。通过对危岩进行测绘和调查,分析形成条件,判断崩塌类型,进行力学计算,评价危岩的稳定程度。总体上,危岩体均处于稳定状态,但是,为了确保工程安全,应采取有效措施进行治理。

Evaluation on Stability of High Slope with Rockfall when Chengdu-Chongqing PDL Bridges over Existing Railway |
| |
| Abstract: | The Xiangtanzi Dual-line Bridge of Chengdu-Chongqing PDL crosses over the existing railway there, inevitably requiring excavation of existing cutting slope where has a large amount of rockfall, and leading to engineering risk. Through mapping and investigation of these rockfall, the stability of perilous rock was evaluated by analyzing the formation condition, deciding the collapse type, and making mechanical calculation. In general, the perilous rock is stable; however, for the purpose of engineering safety, the effective control measures should be used. |
