徐州曹山高填方边坡土工布加固优化设计研究

Study on optimal design for reinforcing high filled slope with geotextile in Caoshan,Xuzhou

城市周边存在废弃采石矿山导致的环境恶化、地质灾害频发、土地资源浪费等现象。随着城市经济快速发展,由于城市用地、景观提升和市民需求等因素,需对废弃采石矿山进行生态环境整治。以徐州曹山采石场矿山地质环境治理工程为例,针对原设计治理方案存在的问题,利用坡率法与土工布结合设置台阶的方法,对其进行多次优化,分析其稳定性、应力场和变形结果,最终得到满足边坡安全等级的治理设计方案。优化后的方案不仅解决了原设计方案存在的问题,还大量减少了土地资源占用,更为经济合理,为类似工程设计提供了借鉴。

The phenomena of environmental deterioration,frequent geological disasters and waste of land resources had caused by abandoned quarries around cities.With the rapid development of urban economy,environmental renovation is needed because of the factors such as urban land use,landscape upgrading and the needs of citizens.Aimed at the problems existed in the former designed plan,the mine geological environment control project of Caoshan quarry in Xuzhou is a typical case of design optimization.On the basis of problems in the original design,this paper used the method of slope ratio method and geotextile to set up steps,optimized them several times,analyzed the stability,stress field and deformation results,and finally obtained the governance design scheme that meets the safety grade of the slope.The optimized scheme not only has solved the problems of the former plans,and has greatly reduced the occupation of land resources and is more economical and reasonable.It can provide a reference for similar engineering design in the future.
