摘要
介绍了钉形水泥土双向搅拌桩及其施工工艺,通过工程实例和试验数据分析,对钉形水泥土双向搅拌桩与常规水泥土搅拌桩在现场施工、桩身芯样无侧限抗压强度以及经济、社会效益等方面进行对比研究,论述了钉形水泥土双向搅拌桩的工程特性。
Authors introduce a new nail shaped bidirectional deep mixing technique in this paper. Practical and comparing tests with the traditional deep mixing method are conducted. Results show the cement-soil mixing piles constructed with the new technique is much better than the traditional one. The SPT and unconfined compression test results indicated that the bidirectional deep mixing pile is more homogeneous either in the horizontal or vertical direction. This new deep mixing method should be extended in soft ground improvement.
