摘要
以东南沿海某土石坝工程坝基软土加固处理为例,基于坝体地质特点,从承载力、沉降控制、成本及环境影响等方面对水泥土搅拌桩复合地基及预制混凝土管桩加固方案进行了对比分析。为兼顾软基处理的经济性与有效性,提出长短桩复合地基的优化方案。现场检测及监测结果表明,长短桩复合地基方案可有效增强地基承载力,控制总沉降量及不均匀沉降。
Taking the soft soil reinforcement treatment of an earth-rockfill dam project in the southeast coast as an example,based on the geological characteristics of the dam body,the cement-soil mixing pile composite foundation reinforcement scheme and the precast concrete pipe pile reinforcement scheme are compared and analyzed from the aspects such as bearing capacity,settlement control,cost and environmental impact.In order to take into account the economic performance and effectiveness of soft soil foundation treatment,a long-short pile composite foundation optimization scheme is proposed.The field testing and monitoring results show that the long-short pile composite foundation scheme can effectively enhance the bearing capacity of the foundation,and control the total settlement and uneven settlement.
