Enhancing the abilities of dust-storm monitoring, predicting and service will be of great benefit and the important significance to China and its people. At present, the comprehensive operation on dust-storm monitoring, predicting and service is still in a preliminary phase, the abilities of operation can’t meet the needs of implementing the real-time and quantitative monitoring and providing the efficient service. The implementation of the project of dust-storm monitoring, predicting and service system will greatly improve the service ability and level for the sustainable development and make a greater contribution to build the better-off society. The first phase project mainly involves monitoring subsystem, predicting, warning and service subsystem; communications and transmission subsystem, etc. In the first phase construction a series of major measures should be taken to address project overall benefits, such as making better use of current monitoring resource, taking into account the standards of data format and project integrative and extensive abilities and so on.展开更多

The construction proceeds in accordance with the master project schedule in preliminary design approved by the central government and the investment can be controlled within the total budget of the preliminary design. The Changjiang Water Resources Commission, taking charge of the general design jobs of the TGP, has consistently paid attention to the project quality in the first place and carried out large amount of investigation, design and scientific research work. This paper makes an overall summarization and presentation on important technical issues in the design, such as dam, powerhouse structure, permanent ship locks, ship lift, project safety monitoring, main river closure and the 2nd stage cofferdam, mechanical and electric design etc., and put forwards a lot of suggestions about optimizing design schemes and measures for smoothing away construction difficulties in accordance with construction progress.展开更多
