针对珠海市某填土边坡工程情况,结合场地工程地质条件的分析,对三种支护方案进行论证后,确定采用“水泥土搅拌桩+钢管桩+挡土墙+钢管注浆”复合支护结构对该边坡进行支护,并简要阐述支护设计参数。工程施工过程及完工后,该边坡未出现滑塌现象,同时满足边坡工程的过程稳定性及长期稳定性要求,验证该支护方案可行。
According to the engineering condition of a fill slope in Zhuhai City and the analysis of engineering geological conditions of the site, after confirming the three kinds of support schemes, it is determined that adopting “soil cement mixing pile + steel pipe pile + retaining wall + pipe grouting ”Composite support structure to support the slope, and a brief description of support design parameters. After the construction process and completion of the project, the slope did not slip down, at the same time, it meets the process stability and long-term stability requirements of the slope engineering and verifies the feasibility of the project.
