Experimental analysis of earth pressure on the light supporting structure;

The application of high-light-retaining structures include prestressed anchor cable poling,anchor slab retaining wall and reinforced earth retaining wall was introduced accordance with its structure compositions,suitable conditions,practical application and field measurement based on the engineering cases used in Yunnan province.

Various new light shoring structures used in the Nan Kun Railway are described with their design and construction,as well as their applicable condition

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.
