摘要:
新孟河延伸拓浚工程南延段河道工程属于平地开河,为满足工程需求,河道设计采用放坡复式断面,沿线局部河段存在深厚淤泥质粉质黏土,该土层力学性能较差,河道边坡整体抗滑稳定安全系数难以满足规范要求。应用水泥土搅拌桩、预制钢筋混凝土方桩与地下连续墙等作为不同河道边坡抗滑措施,并从河道边坡整体抗滑稳定、边坡抗滑措施工程造价等方面进行多角度的对比分析,阐述工程采用地下连续墙进行河道边坡抗滑的优越性,为类似工程设计提供参考。
Abstract:
The south extension section of Xinmeng River Extension and Dredging Project belongs to the river opening on flat ground. In order to meet the engineering requirements，the river channel design adopted the slope-relief composite section. There were deep muddy silty clay in the local reaches along the line. The mechanical properties of the soil layer were poor，and the overall stability safety factor of the river slope was difficult to meet the specification requirements. Soil-cement mixing piles，precast reinforced concrete piles and underground continuous wall and so on were used as a different channel slope anti-sliding measures，and a multi-angle comparative analysis was carried out from the aspects of the overall anti-sliding stability of the river slope and construction cost of the anti-sliding measures of the slope. The advantages of using underground continuous wall for anti-sliding of river slope were expounded，which could provide reference for similar engineering design.
