地铁车站深基坑地下水工程风险分析和控制

地下工程施工技术发展的同时,伴随的施工风险问题日益凸现,亟需有针对性的识别和控制。由于地质条件复杂、涉及的专业多、投资大、建设期长及不可预见因素多等,深基坑地下水工程的风险控制非常关键。通过对国内工程类风险管理现状及其风险分析方法的研究,分析深基坑地下水工程的风险,确定主要影响因素,制订相应控制措施;结合工程案例运用研究成果,具体识别和分析深基坑地下水工程风险,遴选和提出地下水控制方案和技术,形成深基坑地下水工程风险管理体系。

Study on Deep Foundation Pit Underground Water Engineering Risk Analysis & Control of Metro Station

With the developing of underground engineering construction technology,construction risk issue may appear obviously more and more,which needs targeted identification and control urgently.Due to complicated geological conditions,covering more professional fields,large investment,long construction period and unpredictable elements,etc.,risk control is the key to deep foundation pit ground water project.Through the current status of engineering field risk management and its risk analysis method in China,the risk of deep foundation pit ground water project is analyzed on determining main influence factors and forming relevant control measures.Combined with project case and research results,deep foundation pit ground water project risk is identified and analyzed in detail and ground water control plan and technology are chosen and provided,and finally,the whole risk management system is formed.
