简述设计过程中存在的风险,并阐述设计变更对设计风险控制的意义,运用风险管理的基本理论,识别影响设计变更的风险因素,指出不规范的设计变更对设计及工程的风险,并以苏州河河口水闸工程中的设计变更为例,分析来自业主单位、施工单位、监理单位以及设计单位自身的风险,提出控制设计变更引起设计风险的技术与管理水平、方案比选、设计流程控制、设计交底、变更校审等方面的对策措施。 The risk in design process is briefly described. The significance of design change on design risk control is described. The basic theory of risk management is used to identify the risk factors that affect design change. The risk of design change is pointed out based on As an example, this paper analyzes the design changes of Suzhou River Estuary sluice project, analyzes the risks from the owner units, construction units, supervision units and design units themselves, puts forward the technical and management level of design risk control and control, design comparison and selection, design flow control, Design test, change the school trial and other aspects of countermeasures.
