摘要
湿陷性黄土高边坡的处治,是关系到整个项目施工期、运营期的安全性的重要影响因素。如何经济合理的处治湿陷性黄土高边坡一直是工程设计中的一个重难点。研究以实际工程为依托,结合理论分析与既有经验对不同坡率组合的湿陷性黄土高边坡进行了分析。结果表明,各级边坡的坡脚为应力集中点,通过适当放缓边坡坡率、设置较宽的路堑平台可有效的降低集中应力。根据分析结果总结了最佳坡型设计原则,以期为其他项目提供有益的参考。
The treatment of collapsible loess high slope is an important factor related to the safety of the whole project construction period and operation period.How to treat collapsible loess high slope economically and reasonably is always a key and difficult point in engineering design.Based on the actual project,combined with theoretical analysis and existing experience,this paper analyzes the collapsible loess high slope with different slope ratio combinations.The results show that the toe of each slope is the stress concentration point,and the stress concentration can be effectively reduced by appropriately slowing down the slope rate and setting a wide cutting platform.According to the analysis results,the design principles of the best slope type are summarized in order to provide a useful reference for other projects.
