摘要:由于基坑设计理论还不够全面、地表地层的变异以及众多不可预计的复杂问题的出现，施工过程中深基坑工程的造价风险具有多种不确定性。基于多层次灰色理论，针对建筑基坑工程施工阶段的造价风险预测，结合考虑预测指标的关联性，对施工阶段基坑工程造价风险管理评价预测进行详细研究，依托上海某深基坑工程，对其基坑工程施工阶段造价风险进行多层次评价预测，并给出相应风险控制方法，研究成果更好地为建筑基坑工程造价风险预测评价提供理论指导。
Abstract: Because of the uncomprehensive design theory of foundation pit, the variation of surface strata, and the emergence of many other unexpected problems, there are many uncertainties causing the cost risk of deep foundation pit construction. Based on the multi-level grey theory, this paper predicts the cost risk during the construction phase of building foundation pit engineering. Considering the correlated indexes, the evaluation and prediction of cost risk management of foundation pit engineering during the construction phase are studied in details. By using a case study of a certain foundation pit engineering project in Shanghai, the cost risk during the construction stage of foundation pit is evaluated and predicted from multi levels, with corresponding control methods given. The research results can provide theoretical guidance for the prediction and evaluation of the cost risk of building foundation pit engineering.
