摘要
强夯加固期间对上覆填海砂层的软土进行了孔压的监测,分析了强夯时软土中孔压的长消规律和随水平距离的变化及影响范围; 通过对强夯后静力触探试验成果的分析,研究了软土上覆砂层强夯加固的机理,并对强夯的有效影响深度和单点击数问题提出了看法。
By monitoring the pore-water pressure in mucky soft soil during dynamic compaction (DC), the laws of the increment and the dissipation of pore water pressure and the variation of pore water pressure with number of passes and lateral distance are studied. In terms of the results of SCPT after DC, the mechanism of improving filled sand above soft soil with DC is analyzed. In addition, effective depth of influence and number of drops per impact point are discussed.
