1 General Provisions 1.0.1 This standard is formulated with a view to enhance the management on the constructional quality of railway engineering, unify the acceptance of the constructional quality of railway bridge and culvert engineering and assure the engineering quality. 1.0.2 This standard is applicable to the acceptance of the constructional quality of newly-built or reconstructed full gauge railway bridge and culvert engineering for those passenger trains with design running speed of or less than 160km/h that share railways with cargo trains. Alternate standards shall be developed separately for the acceptance of the constructional quality of other railway bridge and culvert engineering as well as the new technologies, new process, new facilities, new materials that are not concerned in this standard. 1.0.3 As the subject of the constructional quality control of engineering, the construction organization shall carry out overall process control on the constructional quality of engineering; the development organization, supervision organization and the investigation & design organization all shall carry out progress control on the engineering quality of each construction phase according to those specified in the relevant regulations. 1.0.4 The construction of the railway bridge and culvert engineering shall implement the sustainable development strategy of national economy, fulfill such works as environmental protection and soil conservation well, utilize the resources rationally and accomplish civilization and security. 1.0.5 The quality data acquired in the inspection and detection on the constructional quality of railway bridge and culvert engineering shall be true and reliable and comprehensively reflect the condition of engineering quality, and the methods and instruments adopted in the inspection or detection shall be in accordance with those specified in the relevant standards. 1.0.6 The

less than those specified in this standard. 1.0.7 The acceptance of the constructional quality of railway bridge and culvert engineering shall not only comply with the requirements stipulated in this standard, but also those in the current relevant national standards. 2 Terms 2.0.1 Constructional quality of engineering The behavior sum of all the obvious and implicated abilities in such aspects as

written form according to the relevant standards, 2.0.3 Site acceptance The materials, members, accessories, and equipments entering into the construction site are inspected according to those specified in the relevant standards to confirm whether whey are qualified. 2.0.4 Inspection lot The inspection body composed of a certain quantity of specimens that are collected according to one same production condition or the specified mode. 2.0.5 Inspection The activity to measure and examine the properties of inspection items, compare the results with those specified in the standard specifications so as to determine whether each property is qualified. 2.0.6 Witness Action of supervision organization or development organization to supervising the completion condition of a certain process of the construction organization on site. 2.0.7 Evidential testing Under the supervision of supervision organization or development organization, the persons concerned of the construction organization sample on site and send the specimens to the inspection organization of corresponding qualification for inspection. 2.0.8 Parallel acceptance testing Examination or inspection actions carried out independently by the supervision organization according to certain proportion by using certain examination or inspection means based on the self checking of construction organization. 2.0.9 Stop and supervision Supervisory activities of the supervisors on site during the construction process of the vital area or critical item of engineering. 2.0.10 Constructional procedure Operating actions with relatively independent characteristics during the construction process or the operating actions with technical intermittent and intermission, and they are the base units of the construction process. 2.0.11 Handing over inspection Action that the construction undertaking party and completing party inspect and confirm whether the construction may be continued. 2.0.12 Dominant item Inspection item playing decisive roles in safety, health, environmental protection and public interest. 2.0.13 General item Inspection items except for the dominant items. 2.0.14 Sampling inspection Inspection carried out by collecting a certain amount of specimens randomly from the site materials, members and accessories, equipments or engineering inspection items of each inspection lot according to the specified sampling scheme. 2.0.15 Sampling scheme Method for determining the sample size according to the behavior of inspection item. 2.0.16 Counting inspection Inspection method for recording a certain property or number of defects of each unit among the sampled specimens. 2.0.17 Quantitative inspection Inspection method for measuring a certain quantitative behavior of each unit among the samples for sampling inspection. 2.0.18 Quality of appearance The external quality of engineering reflected by observation and necessary measurement. 2.0.19 Rework Measures adopting for re-manufacturing or reconstructing the unqualified engineering parts. 2.0.20 Repair Measures adopting for renovating the parts of engineering not matching with those specified in standard. 2.0.21 Common defect Defects without dominating influence on the stressing property or service property of structural member. 2.0.22 Serious defect Defects with dominating influence on the stressing property or service property of structural member. 2.0.23 Compaction pile The pile body formed by the strong vibration and compaction of vibroflot. 2.0.24 Dry jet mixing pile The weak soil is hardened into the stylolitic reinforced soil with integrity, hydro-stability and certain strength by adopting with powder spraying technology, and the reinforced solid and the insitu weak soil layer will form into composite foundation. 2.0.25 Auger injected pile The injection tube with rotatable nozzle is drilled into the precalculated position in soil layer by adopting with driller, the high-pressure will be jetted out from the nozzle to impact, destroy and mix the soil body to form into pile body. 2.0.26 Climbing shuttering Attachable hoisting construction equipment composed of climbing frame and formwork. 2.0.27 Bridge fabrication machine Mechanical equipments used for erecting or casting the prestressed concrete girder in place on the pier by adopting with traversing (formwork) bracket. 2.0.28 Composite girder Girder combined with concrete slab and steel girder. 2.0.29 Stayed cable bridge Bridge with the main girder suspended with many slant wire ropes on the tower with anchors. 2.0.30 Erection by swing method
