丰都至忠县高速公路顺层边坡研究

Study on bed-parallel slope of Fengdu-Zhongxian highway

重庆丰都至忠县高速公路,路线长度32.81 km,顺层边坡特征明显。通过对该项目顺层边坡调查统计,分析了顺层边坡岩体结构及变形破坏模式,结合详细勘察成果、室内试验及现场大剪试验成果,合理确定出了该项目顺层边坡岩体强度参数,为丰忠路顺层边坡设计提供参考依据。

The Fengdu-Zhongxian highway of Chongqing is 32.81 kilometer long with remarkable bed-parallel slope characteristics. Through statistics of bedparallel slope investigation of the project, the rock mass structure and deformation damage mode of the bed-parallel slope were analyzed. In combination with the detailed surveying result, indoor test and site shear test result, the rock mass strength parameters of the bed-parallel slope of the project was determined reasonably, pro- viding reference basis for bed-parallel slope design of Fengdu-Zhongxian highway.
