　　1.工程概況 introduction of project　　略?！　?.膺架施工方案construction scheme of support frame　　2.1.確定膺架方案determining the scheme of support frame　　考慮本工程橋梁總體工程量較少，移動模架進出場困難等因素，故在保證工程質(zhì)量、進度及安全的情況下對大中橋（墩高在8m以上者）施工優(yōu)先考慮采用膺架?！　onsidering the factors that the total quantity of project on bridges is less and that it is difficult for the mobile formwork frame to go in or go out of site, on the base of project quality, progress and safety ensured, the support frame is preferentially used in Large Bridges and Middle Bridges (the height of pier is over 8m.).　　2.2.膺架設(shè)計的要求design request of support frame　　2.2.1.膺架結(jié)構(gòu)必須有足夠的強度、剛度、穩(wěn)定性。　　Enough strength, rigidness and stability　　2.2.2.膺架在承重后期彈性和塑性變形應控制在15mm以內(nèi)?！　lastic and plastic deformation should be controlled within 15mm.　　2.2.3.膺架部分地基的沉降量控制在5mm以內(nèi)?！　ettlement of part subgrade should be within 5mm. 　　2.2.4.當?shù)鼗休d力較低或地表水豐富時優(yōu)先采取挖孔樁基礎(chǔ)方案?！　he digging pile foundation scheme has priority when the bearing capacity of subgrade is low or the water in surface of subgrade is much.　　2.2.4.當?shù)鼗休d力較好，強風化巖層埋置較淺且強風化巖層允許承載力滿足200kPa要求時優(yōu)先采取明挖擴大基礎(chǔ)方案?！　he spreading foundation scheme has the priority when the bearing capacity is good and the burying of the strongly weathered rock stratum is shallow and the bearing capacity satisfies 200KPa. 　　2.3.模板結(jié)構(gòu)及支撐體系　　模板結(jié)構(gòu)是否合適將直接影響梁體的外觀，本工程采用定型鋼模，內(nèi)模采用5mm厚，外模采用8mm厚，全部定型鋼模均由具備相應資質(zhì)的廠家定做?！　hether the structure of formwork is suitable will affect the appearance of girder. The standardized steel formwork is used in this project. The thickness of inner formwork is 5mm, while outer formwork 8mm. All steel formworks are customized by the manufacturer which has relevant aptitude.
