| 摘 要： | 针对津港高速公路垃圾填埋段地基,采用强夯桩式置换法处理,处理过程中开展了施工工艺、地基承载力、沉降观测及回弹模量等试验。试验结果表明:强夯桩式置换处理地基时,应分三遍夯击才能达到桩式置换效果。强夯桩式处理完成后,地基容许承载力满足设计要求,预压荷载作用下地基沉降基本稳定,工后沉降满足路面要求,试验段路基回弹模量满足设计要求。

| Abstract: | The rubbish foundation in Jin-gang expressway was treated by use of the dynamic consolidation of pillar substitution,some test were carryed out such as the constructing technology,foundation bearing capacity,settlement and modulus of resilience.The results of test show that the rubbish foundation should be treated three times by the dynamic consolidation.The bearing capacity of the treated foundation meted the design need,and the settlement of the subgrade drived to the stabilization stage under the pre-con... |
