多道瞬态瑞雷波和探地雷达技术综合评价柔性复合地基加固质量

以夯扩挤密桩柔性复合地基为例,应用多道瞬态瑞雷波和探地雷达技术的优势互补,辅以少量载荷试验方法综合评价柔性复合地基加固效果及均匀性的可行性,并与传统的检测方法进行综合对比。研究结果表明,以2种技术并辅以少量载荷试验方法可以快速有效地半定量-定量评价柔性复合地基加固效果及其均匀性,反映地基加固效果变化的连续性和加固范围,在许多方面比传统的检测方法更加快速、经济、有效、客观。

THE APPLICATION OF MULTI-CHANNEL TRANSIENT RAYLEIGH WAVE AND GROUND-PROBING RADAR TECHNIQUE TO THE INTEGRATED APPRAISAL OF THE QUALITY OF FLEXIBLE COMPOUND FOUNDATION REINFORCEMENT

Exemplified by the densification flexible compound foundation, this paper deals with the feasibility of the application of multi-channel transient Rayleigh wave and ground-probing radar technique assisted by a few loading tests to the integrated appraisal of the effect and uniformity of flexible compound foundation reinforcement, with a comparison with the traditional test methods such as loading test. The results show that this method can rapidly and effectively make semi-quantitative and quantitative appraisal of the effect and uniformity of flexible compound foundation reinforcement and reflect the continuation and range of the variation of foundation reinforcement effect, thus more rapid, effective, economical and objective than the traditional test methods in many aspects.
