摘要
针对深厚度的吹填土地基进行填方挤淤处理尝试,采用变形监测、孔压监测、动力触探测试等多种手段对处理效果进行监测,并对监测效果进行了分析。实验结果表明挤淤深度位置主要在5 m~6 m处,水平向影响范围为20 m~30 m,约为填方路堤的2倍~3倍,而且处理路堤强度不同地方差异较大,后期沉降可能会较大。
Silt displacement by embankment fill is used to try in hydraulic fills improvement,and the effects of the improvement is analyzed with the settlement monitoring,monitoring of horizontal displacement,water pressure monitoring,dynamic penetration test and other monitoring methods.The results show that the compaction depth of place is in the 5~6m department,and horizontal extent of the impact is range of 20 m~30 m,which is 2~3 times of the width of fill embankment.Intensity of different fill embankment is found to have a large respective divergence and post-settlement may be larger.
