1.A floor or roof beam placed between two long beams that supports the ends of the tailpieces.
2.Abstract: By analysing the structure characteristic of the top beam,a suit of working technology process and characteristic are summarized.
4.Aiming at stress analysis of dip angle fully mechanized top-coal caving support in mining, from the technique of designing and mining, put forward technique measurements: reduce gap of support beam; increase the inter-frame jack in neighboring support beam.
5.According to the situation of high output high efficiency face zone of fully mechanized for subleved caving associated equipment ,fire damp prevention and cure,ground behaviour,face zone ranking and roadway layout,this paper designs abut support of face zone,manages abut roof in united support method of combining monomer hydraulic prop and type-πmetal cap, cancels the abut holder ,meets the needs of safety production, and improves the level of high output high efficiency in face zone in further step.
6.Construction Survey Control of Incrementally Launched 8 × 50-m Span Curved Girders of Donghai Bridge Close to Island Side
7.Construction Techniques for 8×50 m Incrementally Launched Box Girders of Donghai Bridge
8.Design and Construction of Steel Launching Nose for Incrementally Launched 8 × 50-m Span Curved Girders of Donghai Bridge Close to Island Side
9.It is proposed that the idea and method to increase resistance,reduce crack and deflection of the cantilever structure by setting up a post-constructed concrete wall between the cantilever beam of the foundation and that of (1st) floor of the frame to form a deep beam with a column on one side.
