| 摘 要： | 排水系统的合理设置对加速土体固结、提高饱和软土地基承载力有重要作用。为探讨盲沟排水对路基下碎石桩加固的软土地基的工程特性的影响,进行了路基试验段的对比试验,并在路堤填筑施工中进行了孔隙水压力和地基沉降测试。试验和工程测试结果表明,渗水盲沟的合理设置可加速地基的固结,提高地基土体的承载力,有效地降低地基中的孔隙水压力,加速路堤填筑的速率。

| Abstract: | The reasonable arrangement of the drainage system plays an important role in accelerating soil consolidation and improving the bearing capacity of saturated soil.To analyze the effect of the blind drainage system on the engineering characteristics of the ground improvement by gravel pile,the contrast tests were carried out on roadbed testing segment.The pore water pressure and the foundation settlement were measured in the process of the roadbed formation.It is shown from the results of the engineering test and measurement that the reasonable arrangement of the blind drainage system could not only accelerate the consolidation,increase the bearing capacity of the soil,but also decrease the pore water pressure effectively in foundation,and run-up the reclamation work. |

| Keywords: | gravel pile composite foundation consolidation soft soil infiltrating blind drainage pore water pressure |
