摘　　要：水泥土搅拌桩施工质量控制一直是其施工管理的重点与难点,目前主要采用对施工过程的监测与工后抽检等方法进行控制。考虑水泥土搅拌桩施工特点,对其施工质量智能评估技术展开深入研究。研究表明:水泥土搅拌桩成桩质量智能评估系统可在施工全程实施施工数据自动采集、保存、异常报警及异地远程实时共享,实现远程监控现场施工,有效保证成桩质量;分析确定了水泥土搅拌桩施工质量分析的关键参数为桩长、每延米水泥掺量及桩身垂直度,建立了水泥土搅拌桩单桩质量即时评估模型,客观、及时地反馈水泥土搅拌桩的施工质量。The quality assurance and control of the soil cement mixing columns are always the critical aspects in the construction management and inspection.Currently,there are two approaches for the QA-QC control:comprehensive monitoring during the installation and integrity tests after the installation.In this paper,the intelligent evaluation system of the construction quality of soil cement mixing columns is developed,and the intelligent evaluation method of soil cement mixing column installation quality is studied based on the soft soil treatment project of an expressway in southern Jiangsu.The results show that the intelligent evaluation system for the soil cement mixing column installation quality can implement the automatic collection,storage,abnormal alarm and remote real-time sharing of the installation data in the entire process of the construction.This system can also be used in remote monitoring of on-site installation and effectively ensure the column quality.The key parameters of the soil cement mixing column installation quality analysis are the column length,the cement content per linear meter and column plumbness.The real-time construction quality evaluation model of the soil cement mixing column is established to objectively and timely feedback for the installation quality of the soil cement mixing column.
