Next,three aspects were considered as key technology and research challenges of bascule bridge deck surfacing here,(i)development on light paving material and research on thin deck surfacing system,(ii)numerical simulation of the mechanical properties of bascule bridge deck surfacing based on long cantilever structure and contact behaviors between interfaces,(iii)bonding layer material testing.

This paper puts forward a new structural form of adding layers on and expanding subsistent houses,presents the application and the characteristics of the bearer point related to the huge framed cantilevered structural system and summarizes the main advantages of adding layers by cantilever structure.

The intake platform in upstream and the arc-shaped pier in downstream of the deep outlet are supported by the cantilever structure outside of the dam body.

The connected cantilever structure is the core part of the building,forming a dimensional "L" shape.

The moment calculation method for cantilever sheet design under the concentrated loads such as the rectangular,triangular,circular and polygonal within the effective distribution scope proposed in code,are predicted.

Influence of cantilever structure on the characteristic of strain-type displacement sensors;
