【摘要】：強(qiáng)震后,科學(xué)、快速地?fù)屚ǜ吡叶绕D險(xiǎn)山區(qū)交通生命線是一個(gè)難點(diǎn)。以汶川地震災(zāi)區(qū)公路搶通工程為研究背景,對(duì)高烈度艱險(xiǎn)山區(qū)公路震害評(píng)價(jià)等級(jí)體系及處治技術(shù)進(jìn)行研究。根據(jù)公路震害的破壞特點(diǎn)、恢復(fù)難易程度,并結(jié)合公路搶通的原則、特點(diǎn)及目標(biāo),通過(guò)分別建立搶通階段橋梁、隧道及路基震害的評(píng)價(jià)等級(jí),最終建立了搶通階段公路震害評(píng)價(jià)等級(jí)體系。公路A、B級(jí)震害不需處治;C級(jí)震害處治技術(shù)為:橋梁半幅限行,隧道及路基采用除危、清方;D級(jí)震害處治技術(shù)為:橋梁臨時(shí)支撐或限位、橋上架橋,隧道噴混凝土或安設(shè)型鋼鋼架臨時(shí)支護(hù),除危、清方,巖石松動(dòng)爆破;E級(jí)震害處治技術(shù)為:埋設(shè)涵管、設(shè)置槽渡、搭設(shè)便橋、硐室定向爆破及便道繞避。
[Abstract]:After strong earthquake, it is a difficult point to seize the transportation lifeline of high intensity and dangerous mountain area scientifically and quickly. With the background of highway rescue project in Wenchuan earthquake area, the evaluation grade system and treatment technology of highway earthquake damage in high intensity mountain area are studied. According to the damage characteristics of highway earthquake damage, the degree of recovery is easy, and combined with the principles, characteristics and objectives of highway robbery, the evaluation grade of earthquake damage of bridge, tunnel and roadbed is established separately. Finally, the evaluation grade system of highway earthquake damage is established. The measures to deal with the earthquake damage of the Agna B earthquake are as follows: the bridge is limited by half amplitude, the tunnel and subgrade are treated by danger removal, and the treatment technology of the earthquake damage of the Qing Fang and D magnitude is: temporary support or limit of bridge, bridge erection on the bridge, The temporary support of shotcreting concrete or steel frame in the tunnel, removing danger, clearing the square and loosening rock blasting are as follows: buried culvert pipe, groove crossing, construction of stool bridge, chamber directional blasting and sidewalk avoidance.
