| 摘 要： | 以重庆轨道交通十号线朱家湾车场为依托工程,采用现场原位大型直剪试验,得到岩体软弱结构面的强度参数,与《建筑边坡工程技术规范》GB 50330-2013中的软弱结构面抗剪强度指标推荐值进行对比。运用有限元强度折减法对该边坡典型断面的破坏模式和稳定性进行分析,其结果显示该边坡为欠稳定边坡,易沿层面发生滑动破坏,针对分析结果提出了相应的加固和支护措施。

| Abstract: | According to in-situ direct shear tests of the bedding rock slop of Zhujiawan yard of Chongqing rail transit line 10,the shear parameters of weakness structural plane are comparing with recommended value of the national standard Tech-nique Code for Building Slope Engineering (GB 50330-2013).Using strength reduction finite element method to analysis the failure mode and stability of the slope ,result shows that the slope is not stable ,and may sliding along bedded plane of rock mass.Finally,the corresponding suggestions of supporting systems of slope are throw out based on the stability analysis results . |
