, which frequently occur on the prefabricated components of port engineering construction, the prevention and control measures are put forwar

Combined with modification work of Shengli Bridge the quality control measures of prefabricated components are elaborated.

Analysis on transport,storage and loading quality control of precast members;

Repair of defects on the appearance quality of precast members;

Based on the construction conditions and the characteristics of the bridge,the new technique,the new structure and the new technology of the highway and rail tragic constructed together,the large-span ca- ble-stayed bridge,the large-span built-up beam,the large-sized prefabricated member and the main beam assembled by segments are deve.

The use of precast concrete structures in office building in Singapore has been discussed,especially the analysis method of the overall building structures,the design method of the precast elements and the connection details between the precast elements.

The analysis methods of the strength of the precast elements and the connections between the precast load bearing walls, precast slabs, precast beams and precast columns are introduced.
