摘要
在软土地基的特点及常规的处理方法的基础上,以野马坝试验工程为依托,首次使用由振冲法发展而来的振动沉管碎石桩加固泥炭土地基,并对其施工工艺及加工过后的效果进行研究总结。通过试验证明振动沉管碎石桩在排水性能、减少地基不均匀沉降、提高地基承载力等方面具有卓越的成效。其结论可为类似工程提供参考。
Based on the characteristics of soft earth foundation and conventional approach, relying on projects mustang dam, the first time that uses vibro replacement stone columns developed by the vibro flotation method in soft earth foundation treatment. The construction technology and the effects of the reinforcement on soft clay ground are concluded. Test shows that vibro replacement stone columns in the drainage performance, reducing differential settlement of foundation, improving the bearing capacity and so has excellent results. The conclusion can provide reference for similar projects.
