摘要: 为研究隧道锚碇围岩的力学性质,以某悬索桥岩基——蚀变二长花岗岩为研究对象,开展了室内试验及现场原位试验,得到其物理力学参数试验值 。结合现场实际地质情况,给出了蚀变二长花岗岩的物理力学参数建议值。研究结果不仅可为悬索桥隧道锚碇围岩稳定性分析提供依据,也可为类似工程 条件岩体力学性质的研究提供借鉴。

Abstract: In order to study the mechanical properties of tunnel anchorage rock,the rock foundation of a suspension bridge—the altered adamellite was taken as an example to launch the indoor and in-situ tests,and the test values of its physical and mechanical parameters were obtained.According to the actual geological conditions in the field,the proposed values of the physical and mechanical parameters of the altered adamellite were given.The research results not only provide a basis for the stability analysis of the surrounding rock mass of the tunnel anchorage of a suspension bridge,but also provide a reference for the study of the mechanical properties of rock mass under similar engineering conditions.

Key words: bridge engineering, geotechnical engineering, suspension bridge rock foundation, rock mechanical test, rock mechanical parameters
