目前对软基加固效果一般用静载荷试验检测,但因承载板面积较小,以点代面,存在局限性。文中利用高密度电法对介质含水性及密实状态效果显著的特点,对粉喷桩处理软基的效果进行了检测,测试结果表明:在处理前,测线范围内视电阻率较小,层面平行;土体经粉喷桩处理后,电阻率局部出现明显扭曲,测线范围内含水率变小,视电阻率变大,密实度增加,软基处理效果明显。高密度电法配合静载荷试验进行检测,点面结合,互为补充,评价结果比较全面、科学,为软基加固效果检测提供了一种新方法。
At present, the reinforcement effect of soft foundation is generally tested by static load test. However, due to the small area of the carrier board, the point substitution surface has limitations. In this paper, the effect of high-density electrical method on the water-bearing and dense state of media is studied. The effect of soft foundation treated with DJM pile is tested. The results show that the apparent resistivity is small before the treatment, After the soil was treated by DJM pile, the resistivity was obviously distorted locally. The moisture content in the measuring range became smaller and the apparent resistivity became larger and the compaction increased. The effect of soft foundation treatment was obvious. High-density electrical method with static load test for testing, point-surface combination, complement each other, the evaluation results are more comprehensive and scientific, to provide a new method for testing the reinforcement effect of soft ground.
