摘要 离岸人工岛施工监测控制网的建立可以借助于海上测量平台。针对海中刚性结构的测量平台易受温度、湿度、气压、风力、潮汐等外界因素影响,从而影响监测控制网精度的问题,对其进行专项研究。基于深中通道西人工岛工程监测项目,通过合理控制技术指标,设计一种跨海高差传递方法,经过精度分析验证了该方法的可行性,可建立满足二等技术要求的施工监测控制网,并给出提高精度的相应措施,为离岸人工岛施工监测提供借鉴。 The construction of monitoring and control network of offshore artificial island can be established by means of offshore measurement platform.We carry out a special study on the problem that the measuring platform of offshore rigid structure is susceptible to external factors such as temperature,humidity,pressure,wind force,tide and so on,which has a great influence on the precision of the monitoring and control network.Based on the monitoring project of west artificial island project of Shenzhen-Zhongshan Bridge,we propose a transference method of height difference through reasonable controlling technical indexes,verify the feasibility of the method by the analysis of precision,realize the establishment of construction monitoring and control network which meets second-class technical requirements,and give several measures to improve the precision.It can provide references for the construction monitoring of offshore artificial island.
