Practice And Study On Composite Frame Of Support In Foundation Engineering

The protect of shoring foundation pit is an old but times specialty Geotechnical engineering problem, it includes to round the design of protect the system, construction and soil the square opens to dig, is a tool syntheses very strong systems engineering .The pit engineering involves the soil mechanics, base foundation and flows to change to learn, structure mechanics, play several courses, such as mechanics of, reinforced concrete structure and the steel structure...etc., not only need the knowledge of the rock soil engineering, but also need the knowledge of the structure engineering, all need the comprehensive processing in the whichever pit engineering.In the city deep the near side that the pit engineering often is placed in the intensively current building, road bridge, underground pipeline, the subway tunnel or person to defend the engineering, although belong to the temporary sex engineering, but its technique complexity is far more than the foundation structure of the permanence or the upper part structure, having a little bit the immodesty, not only will endanger the pit safety, and the meeting and close by construction or purchase build the thing, the road bridge and various underground facilities, resulting in the huge loss. Speak from a different angle, the deep pit engineering the design need with many technique parameters that open to dig the construction is basis, but open to dig construction process in usually will cause to pay to protect the dint inside the structure ands to move and the outside soil body inside the pit of transform to take place various accidents variety, the traditional design method is hard to set in advance or the after the event handle. Under the circumstance that...
