灰色-层次分析法在基坑支护方法选取教学中的应用

为了保证基坑工程安全,降低基坑支护工程造价,满足基坑工程施工要求并减少对周边环境的影响,基坑边坡需采用恰当的支护方法。基坑支护方法选用是一项受多种因素制约的综合性系统工程。文章以实际工程为例,在考虑支护结构、施工及环境影响等因素的基础上,通过层次分析法确定各影响因素权值,采用灰色分析法对支护方法进行决策分析。该方法应用于基坑工程教学中,取得了良好的教学效果,为基坑支护方法合理的决策分析提供了新途径。

In order to ensure the safety of foundation pit engineering,reduce the cost of foundation pit supporting engineering,meet the construction requirements and reduce the impact on surrounding environment,it is necessary to adopt appropriate methods for decision analysis of supporting scheme.The decision of foundation pit supporting scheme is a comprehensive project restricted by many factors.As an example of practical engineering in the paper,on the basis of considering the supporting structure,construction and environmental impact factors,the weight of each factor is determined by AHP and decision analysis on foundation pit supporting scheme is done by gray analysis method.This method has been applied to the teaching of foundation pit engineering and achieved good teaching effect.It provides a new way for reasonable decision analysis of foundation pit supporting schemes.
