【摘要】 通过基于监测的深基坑工程风险辨识、风险估计、风险评价和风险控制研究,建立了一套可操作性强的深基坑工程风险管理系统。利用专家调查法(包括德尔菲法)、故障树分析法、核对法等对深基坑工程的风险因素进行辨识;提出了以主观估计法为主的深基坑工程风险估计方法;建立了基于监测的深基坑工程风险评价体系,包括风险概率分级标准、风险损失等级分级标准、风险评价矩阵、风险接受准则和风险等级,并建立起风险等级与监测等级的关系;提出了以风险跟踪和风险预警为主导的风险控制方法。更多还原

【Abstract】 According to the study on risk identification,risk estimation,risk assessment and risk control of deep foundation engineering based on monitoring,a set of feasible risk management system of deep foundation engineering is built up in this paper.The expert surveys method(including Delphi),fault tree analysis,checklist are used in identifying risk factors in deep foundation engineering.The risk estimation method of deep foundation engineering based on subjective estimation is proposed.This paper has established a monitoring-based risk assessment system on deep foundation engineering,including the standards of risk probability classification and risk loss level,the risk assessment matrix,the risk acceptance criteria and risk levels.The relationship between risk level and monitoring level is set up.The risk control method on risk tracking and risk early warning is put forward.更多还原
