Description
Technical field
The invention belongs to Impacts Evaluation of Urban Tunnel engineering fields and urban operating mechanism technical field, more particularly to a kind of gravity type
Assemble concrete retaining wall.
Background technique
Slope project is in especially important status in entire great civil engineering, the reason is that slope project amount is big, technology
Difficulty is big, accident rate is high.Slope project object is rock mass or the soil body, what Rock And Soil was a naturally occurring, cannot artificially be manufactured, feature
Be: property varies in different localities, because of Shi Eryi；The mankind understand cannot be detailed；Mechanics parameter can not accurately be provided；Design level is because of people
And it is different.These features, which exist, brings great difficulty to engineering construction, as a result, improper to Rock And Soil assurance, accident rate is big
(it is reported that side slope accident rate accounts for 70% or so in architectural engineering)；Design scheme is different, and cost variance is big；Geological conditions variation
Greatly, lack the slope support method of economical rationality in many cases.Currently, the structural body master used in tall earth fill improvement
Have: cantilever pile retaining wall, anchorage pile retaining wall, gravity retaining wall, reinforced earth retaining wall, taper pile self-balancing retaining wall etc..
Wherein: when gravity retaining wall height is greater than 8 meters, quickly, economy is particularly poor for high retaining wall for engineering cost increase；
The moment of flexure of cantilever pile retaining wall is maximum one kind in all structure types, so cost is also very high；For tall and big retaining wall
For, in contrast, the cost of anchorage pile retaining wall is lower than the above two, and taper pile self-balancing retaining wall cost is minimum, so closely
Both retaining walls are widely applied over year.Wherein, anchorage pile retaining wall needs anchor brace members, and taper pile self-balancing is kept off
Cob wall does not depend on anchor brace members, has bigger advantage in terms of economy and geological conditions adaptation.Taper pile self-balancing retaining wall technology
Key be: using taper pile supporting reduce side slope thrust；The recurvation square balance side slope generated using Foot of Upper Retaining Wall gravity is pushed away
Power moment of flexure.This structure has the characteristics that reasonable stress, and slope project cost is greatly lowered, and the dependence to geological conditions
Very little, so applicability is very strong.Also just because of this structure, it is desirable that side slope to have constant slope (generally with plumb line angle
20 degree), it means that slope supporting will account for certain space.But certain slope projects without slope space, taper pile self-balancing
The application of barricade is just restricted.Retaining wall refers to bearing Roadbed Soil or the hillside soil body, prevents from banketing or soil deformation unstability
Structure.In the construction that road grade bridge leads the way the duration in large- and-medium size cities, road shoulder retaining wall is constructed due to by short time limit.With
The limitation of Adjacent Buildings just makes it that must construct using gravity type assembly concrete retaining wall.In addition, for those ground
Base condition difference and the area for lacking building stones, since it requires that wall is light and small, it is low to take up an area less and foundation bearing capacity, using weight
It is its optimal selection that power formula, which assembles concrete retaining wall,.Gravity type assembles concrete retaining wall, due to that engineering can be made to shorten
Duration, therefore the negative influence that its construction generates periphery social environment and ecological environment is smaller, it thus just can be by city road
The traffic pressure of road construction is alleviated, and so, just has important facilitation to construction low-carbon conservation-minded society.
