摘要
通过孔压观测、标贯试验以及室内试验研究了公路加宽段强夯加固的处理效果,试验结果表明粉细砂地基采用强夯法进行处理是合理的,强夯法对本路段的影响深度可以达到夯击点面下8 m^10 m,根据孔压测试的情况,各遍夯击之间的间隔时间虽较短,也是适宜的,未对施工造成不良影响。
The dynamic consolidation effect of municipal road widening section was studied with pore pressure observation,standard penetration test and interior test.The test result indicated that dynamic consolidation treating in fine sand foundation was rational,the dynamic consolidation influencing depth on the road reached 8 m～10 m under consolidation point,according to pore pressure test situation,the time interval between various consolidations was short and proper,which had not defective influences on construction.
