航道驳岸软基处理深搅桩施工质量抽检评定方法的实践

Sampling evaluation of deep mixing piles′ construction quality for channel revetment′s soft ground treatment

结合在航道驳岸软基处理中深搅桩施工质量抽检评定方法的实践,介绍以标准贯入击数、桩身水泥土无侧限抗压强度及芯样状态描述为评分参数的质量检测评分方法。实践表明,这种以定性描述和定量计算相结合的质量评定方法是行之有效的。

Combining the real practice of sampling evaluation for the construction quality of deep mixing piles in channel revetment＇s soft ground treatment, this paper expounds the quality inspection and evaluation method which takes the count of standard penetration test, soil-cement piles＇ unconfined compressive strength and the core sample description as the count score parameters. It is proved by practice that this quality evaluation method which combines qualitative description with quantitative calculation is very effective.
