摘要
三峡工程安全监测系统规模宏大、技术复杂 ,在初步设计基础上有必要开展优化工作。根据“突出重点 ,兼顾全面 ,统一规划 ,分期实施”的监测布置总原则 ,针对不同建筑物的结构和基础特点 ,以变形监测、渗流监测、应力应变及温度监测为重点 ,确定优化目标 ,开展优化研究 ,取得了明显的成果 ,其中变形监测、渗流监测的仪器、设备数量减少约 1/ 2 ,应力应变和温度监测减少 2 / 3 ,水力学和动力监测约减少 1/ 2。这些研究成果 ,绝大部分已分别在招标设计和施工详图中被采用。
The scale of the Three Gorges Project's(TGP's) safety monitoring system is enormous and its tech nology complex.On the basis of primary design,it is necessary to develop optimum research for this system.Based on the general principle of monitoring arrangement of 'laying emphasis on key points,considering overall situation,uniting planning and implementing plan by stages',aiming at the features of the different structures and their foundations,taking the deformation monitoring,seepage monitoring,stress monitoring and temperature monitoring as key points,the optimum objectives were determined,researched and good results obtained.Among them,the number of instruments used for deformation monitoring and seepage monitoring,as well as those used for hydraulics monitoring and dynamic monitoring,may be reduccd by about 1/2,and those used for stress monitoring and temperature monitoring,by about 2/3.Most of the study results were adopted in the tender design and construction detail drawing.
