摘要： 城市快速公路两侧的山体边坡对道路的安全运营具有重要影响，必须进行安全防护，对已有滑动趋势的必须进行灾害治理。以华南快速干线上某山体滑坡为例，分析了此滑坡治理工程的要点，并针对这些问题提出了应对措施，在此基础上提出了滑坡工程的治理方案，详细介绍了选择此方案的依据与方案的具体措施，并采用有限元软件对此滑坡工程的治理过程进行了数值模拟。数值分析的结果表明此滑坡治理方案合理有效，经过治理该滑坡体可处于安全和稳定状态，不再对下方城市快速公路造成安全威胁。

Abstract: Landslides on the slopes at both sides of the city expressway might have a significant impact on the safe operation of the roadway. It is therefore urgent to provide protective measures for areas that have landslide hazard potentials and provide mitigation measures for areas that have slides occurred. This paper provides a case history of landslides at a city expressway in South China. The characteristics of the landslide projects are introduced and the key aspects of the mitigations are proposed. The landslide process was simulated with the finite element method. The numerical analysis indicates that the landslide mitigation method is effective and the safety hazard to the roadway has been eliminated.
