The invention discloses a bridge full-life-cycle BIM model information base construction method based on two-dimensional EBS coding, and the method comprises the steps: carrying out the layer-by-layerdecomposition of a target bridge according to a structure, carrying out the coding of a result obtained through decomposition, and obtaining a structure code, and enabling a result at the lowest layer of decomposition to be a bridge member; determining information needing to be recorded based on the bridge component and encoding the information needing to be recorded to obtain an information code; and in the full life cycle of the bridge engineering activity, inputting corresponding bridge information based on the structure code and the information code, and establishing a bridge full life cycle BIM model information base. The method is applied to the whole life cycle of the bridge; a unified information carrier is provided for BIM technology information integration; integrated managementof bridge components and information in each stage is realized; the two-dimensional EBS encoding system can effectively record information and express the information in the BIM model, expresses thetwo-dimensional EBS of the bridge in the BIM model in an attribute set information extension mode, and can comprehensively record the information generated by the bridge in the full life cycle in detail.

The invention provides a full life cycle carbon emission accounting method for an automobile engine cylinder cover. The method comprises the following steps: 1, determining an accounting target, a function unit and a boundary range; step 2, list analysis; step 3, influence evaluation; and 4, result interpretation. According to the method, the life cycle carbon emission of the automobile engine cylinder cover is calculated by adopting an equivalent coefficient method, and factor correction is performed on main materials, so that the method can be better close to the actual production condition, meanwhile, the carbon reduction contribution degree of the recycled materials to the full life cycle of the engine cylinder cover can be identified, resource recycling is promoted, and the economic benefit is increased. Carbon emission of engine cylinder cover products is reduced, enterprises are helped to analyze carbon emission key points, the carbon emission reduction direction is identified, and the purpose of protecting the environment is achieved.
