JTG 3363-2019 Specifications for Design of Foundation of Highway Bridges and Culverts
1General Provisions
1.0.1 The Specifications is developed for regulating the design of the foundation of highwaybridges and culverts to ensure the quality of construction projects.
1.0.2 The Specifications is applicable to the design of foundations of highway bridges andculverts to be built on all classified highways,
1.0.3 The design of the foundations shallfollow the principles of adjusting measures to localconditions, using local materials , and saving fesources.
1.0.4 The type of foundations of highway bridges and culverts shall be reasonably selected basedon geological, topographic, hydrological, and construction conditions, as well as the loads.materials, and types of superstructures and substructures, ete.
1.0.5 The foundations shall be designed based on the relevant survey data. The survey data shallaccurately feflect the topography, landform, strata, adverse geology, physical and mechanicalproperties of rock and soil, underground water, ete.
1.0.6 Durability design shall be conducted for foundation structures in accordance with therequirements of the relevant specifications.
1.0.7 In addition to the Specifications , the design of foundations of highway bridges and culvertsshall also comply with the provisions in the current relevant national and industrial standards.
2Terms and Symbols
2.1 Terms
2.1.1 ground
The soil body or rock mass that bears the structural actions.
2.1.2 foundation
Components of substructure that transfer《anous actions of structure to the ground.
2.1.3 characteristic value of subsoil bearing capaeityThe pressure value corresponds to the specified deformation inner the linear segment in the curve ofsoil pressure-deformation of ground measured by loading test. It is also known as characteristicvalue of ground bearing capacity
2.1.4 jointThe crack of fissure without apparent displacement of the rock stratum between the two sides of thefracture plane of the rock mass.
2.1.5 bearing stratum
The stratum that directly bears the action of the foundation.
2.1.6 underlying stratum
The stratum with a certain depth below the bearing stratum, which is compressed or possibly shear-damaged.
3General Rules
3.0.1 The bearing capacity and stability of the foundations of the highway bridges and culvertsshall be checked, the settlement shall also be checked if neeessary.
3.0. 2In checking the ultimate limit state of a foundation, the design safety level and importancefactor of the structure shall be determined in accordance with the provisions in the current GeneralSpecifications for Design of Highway Bridges and Culers ( jTG D60)
3.0.3 In the design of a foundation, the requirements for construction and environmentalprotection shall be considered.
3.0.4 The materials of the fbundation structures shall be designed to comply with the provisionsof relevant structural design speeifications.
3.0.5 The bearing depths of the foundations of highway bridges and culverts shall be determinedby the types of foundations, and by the comprehensively consideration of the adverse influences ofgeology , hydrology , climate , and human activities during the construction and the service periods.
