摘要

摘要: 岩质高边坡稳定性的分析评价涉及工程地质学、岩体力学、计算科学等多学科交汇的问题,是一较为复杂的系统工程问题。在系统分析岩质高边坡赋存的地质背景和环境条件的基础上,采用系统分析评价、综合集成的方法应是研究分析和解决该问题的有效和最佳方法。针对漳龙高速公路石崆山Ⅱ段岩质高边坡工程,在系统分析边坡工程地质特性的基础上,采用赤平极射投影法和有限单元(FEM)法等,进行综合评价和系统分析,获得的稳定性结论,已正常运营使用若干年,反映了系统分析,综合评价方法是成功和有效的。它表明,综合评价、系统分析应是岩质高边坡稳定性评价分析的重要途径;它的综合内容和集成方式及其完善与工程实用性,有待进一步深入的研究和工程实践的运用及其经验的积累。

Abstract: Stability of high rock cut slope is a complicated systematic project,which relates to the engineering geology,rock mechanics,and computation science,etc.On the basis of carefully studying the geological background and environmental conditions,systematic analysis and evaluation,comprehensive integration method are the best method for effective analysis,research and solution of this problem.For the case of Zhang-Long expressway Shi Kongshan No.Ⅱ section high rock slope,on the basis of the systematic analysis of engineering geologic properties,Stereographic polar projection method,and Finite Element Method(FEM) are used in comprehensive evaluation and systemic analysis,by which the slope stability results are obtained,and then are accepted and adopted by design and construction corporations.The slope has already kept in safe operation for several years after its completion which shows that this comprehensive evaluation and systemic analysis are successful and effective,and can be an important pathway of stability evaluation of high rock slope.Its comprehensive contents and integrated mode and its perfection and engineering practicability need further research,engineering practice and experience accumulation.
