Abstract:In order to replace the cable-stayed cables, some cable-stayed Bridges generally adopt the double casing saddle structure. On the basis of elaborating the structural design requirements and force characteristics of the saddle area of the cable tower, the research contents and some suggestions for improvement in the design of the saddle area of the cable tower are put forward, which can be used as reference for design.

Abstract:This paper focuses on the analysis of the weak link in the design of Sujia-Hangzhou expressway bridge and culvert structure, and puts forward the optimal design scheme.

Abstract:Bridge structure is a typical irreversible structure, affected by natural factors such as corrosion, erosion, prestress loss, etc., and unnatural factors such as accidental damage, overload, cracking, etc. Once built, its structural performance will continue to decline with the growth of operating time. If appropriate reinforcement or grade improvement measures are taken, its structural performance will be improved and the bridge life will be extended Long.

Abstract:This paper introduces the application of LSD hydraulic lifting system in large weight and long span continuous beam rotating lifting project, and introduces the lifting balance algorithm, computer control and adjustment process of continuous beam rotating lifting and lifting construction method.

Abstract:In the process of construction, prestressed concrete hollow slab is prone to crack. The influencing factors are: temperature stress, raw material quality, construction technology and so on. Strengthening the management of the main processes in the construction process, especially the curing of concrete, is the key to eliminate the surface cracks of concrete.

Abstract:This paper comprehensively introduces the prefabrication process of U-shaped beams and the application of construction control points in Aljunied Bridge of PIE Expressway in Singapore. The layout, management and construction personnel of the prefabrication yard are described in detail, and the construction method combining advanced modern equipment and traditional construction technology adopted in this project is analyzed.

Abstract:This paper is based on the data of "load-distributed anchorage structure" collected from the author's visits to Korea, Japan, Australia, the United States and other countries in 1986, and the data collected from the technical exchanges with experts and scholars in the geotechnical anchorage field in Taiwan, and focuses on the relevant situation of Japan and South Korea for geotechnical anchorage engineering technology Personnel reference.
