变权层次分析法在深基坑支护方案优选中的应用

深基坑支护工程是一个非常复杂且技术性很强的系统工程，它涉及环保、经济、施工的合理性及便捷度等多个方面; 因此，选择一个安全、可行的深基坑支护方案十分重要。本文通过改进层次结构模型并利用变权层次分析法对深基坑支护方案进行优选，弥补了传统层次分析法可能导致方案复合排序失效的不足，使评价结果更科学合理。工程实例应用表明该方法具有实用性。

Application of Dynamic Weight Analytic Hierarchy Process Method to Optimization of Bracing Projects for Deep Foundation Pit

Deep foundation pit bracing is a complex and highly technical project. It relates to many aspects, such as economy, environmental protection, reasonable and convenient construction. Therefore, it is very important for a deep foundation pit bracing project to choose a safe and feasible scheme. An effective method to optimize bracing projects is proposed for deep foundation pit by improving a hierarchy model of project evaluation and using the dynamic weighted AHP method. It can avoid the problem of unreasonable sorting result caused by the traditional AHP method and make evaluation result more reasonable and scientific. Finally, an application example shows that the method is practicable.
