【摘要】 上海打浦路隧道复线工程浦西明挖段结构中山南路匝道全线位于原日晖港河道中,必须进行填浜清淤处理。简述了原日晖港的驳岸、工程地质条件及淤泥情况。分别介绍了内支撑清淤、淤泥固化、抛石清淤及蓄水吸淤等4种设计方案,经比选,确定采用蓄水吸淤方案。最后,介绍了3个不同断面的工后沉降理论分析结果。根据通车后实际观测结果,隧道与道路运营状况良好,未出现明显的裂缝、差异沉降。更多还原

【Abstract】 With the background of Shanghai Dapu Rd.Tunnel Complex Line project,the whole line of South Zhongshan Rd.ramp(belonging to Puxi open cut section),located in primary river channel of Rihui Port,should be made filling creek & dredging treatment.Revetment,engineering geological condition and sludge condition of primary Rihui Port are discussed briefly.Four design plans are introduced including internal supporter dredging,sludge solidification,riprap dredging and water storage absorbing sludge.Through comparison & selection,the plan of water storage absorbing sludge is determined to use.Finally,the post-construction settlement theory analysis results of three different cross sections are introduced.According to practical observed results from being opened to traffic,the running conditions of tunnel and road are great without appearing obvious cracks and relative settlements.更多还原
