碎石桩作为处理软弱地基土的一种有效手段,往往需要对其试验效果进行分析。论文以秦沈线高填方地基处理工程为背景,介绍了碎石桩法加固软弱土层的现场试验,并对碎石桩处理后复合地基的加固效果进行了检测分析。包括碎石桩体和桩间土检测,最后综合动力触探测试及载荷试验检测结果得出,碎石桩对本工程软弱地基的处理能达到预期的加固效果,其复合地基承载力高于设计要求。 As an effective measure to treat soft soil, gravel pile often needs to analyze its test results. Based on the project of high embankment treatment in Qinling-Shenyang Railway, the paper introduces the field test of reinforcing the soft soil by the gravel pile method, and analyzes the reinforcement effect of the composite foundation after the gravel pile is treated. Including the gravel pile and soil testing between piles, the final comprehensive dynamic penetration test and load test results show that the gravel pile on the weak foundation of the project to achieve the expected reinforcement effect, the composite foundation bearing capacity higher than the design requirements .
