The soil nail & anchor of complex support structure was applied in a cut slope project in Hunan,which appeared distability accident in 2005.

The time-dependent property of cohesive soil pressure of retaining structures;

Calculation of earth load on landslide retaining structure based on planar sliding

Anchor anti-slide pile is regarded as a kind of retaining structures made up of anti-slide pile and anchor,at the same time,the anti-slide pile of this structure is also regarded as the beam laid on the elastic foundation and the tension of anchor is conducted as a concentrated force loaded on the pile.

Through a few typical construction examples, the paper fully demonstrates effectiveness and advantage of cement clay mixing pile in supporting and retaining structure of foundation pit and sums up some successful experiences for reference and selection.

Theoretical analysis and engineering application of supporting structure of framed pre-stressed anchor bars;

Optimum design of grillage supporting structure with pre-stressed anchor bars on loess slope;

Analysis and design of supporting structures on loess slope are very complicated problems.

Through the in?situ test,abtaining the phenomenon that the efficient pressure in mucky loam arises sharply when the displacement of support structure reaches to a certaint value.

Integrating road cut slope engineering of Chongqing City of China,the author studies new type support structure of cut slope (self support structure system),its mechanics calculation model and method of design,and construct art etc.
