【摘要】:橋梁施工堅(jiān)持"安全第一,預(yù)防為主"的基本原則.為了保障橋梁施工的安全,盡量避免人員傷亡和財(cái)產(chǎn)損失,將橋梁施工劃分為若干個(gè)工序,對(duì)每個(gè)工序進(jìn)行風(fēng)險(xiǎn)評(píng)價(jià).利用層次分析法建立橋梁樁基礎(chǔ)施工安全評(píng)價(jià)指標(biāo)體系;結(jié)合數(shù)據(jù)包絡(luò)分析評(píng)價(jià)方法,通過(guò)移動(dòng)最大風(fēng)險(xiǎn)曲面,對(duì)各決策單元風(fēng)險(xiǎn)等級(jí)進(jìn)行排序.以承秦高速石門(mén)寨連接線東洋河大橋樁基礎(chǔ)施工工序?yàn)槔M(jìn)行了方法驗(yàn)證.通過(guò)實(shí)證,該方法方便實(shí)用,有很好的實(shí)用價(jià)值.
[Abstract]:Bridge construction adheres to the basic principle of "safety first, prevention first". In order to ensure the safety of bridge construction and avoid casualties and property losses as far as possible, the bridge construction is divided into several processes, and the risk assessment of each process is carried out. The safety evaluation index system of bridge pile foundation is established by AHP, and the risk grade of each decision making unit is sorted by moving maximum risk surface with data envelopment analysis and evaluation method. Taking the pile foundation construction procedure of Dongyang River Bridge on Chengqin High-speed Shimenzhai connection Line as an example, the method is verified. Through demonstration, this method is convenient and practical and has good practical value.
