摘要
软土路基上修筑的结构物往往容易产生盆形沉降,沉降后沉降缝开始增宽,在车振动、水压力或其他外力作用下,路基填料从沉降缝处流失,影响路基及结构物自身的稳定。对沉降结构物台背土体进行压浆加固,使台背土体成为整体后,形成对结构物台身的侧向支护,可有效地解决路基及结构物自身的稳定问题。
The soft soil roadbed structure built tend to produce a basin shaped settlement,suture dehiscence broadening settlement,in the vehicle vibration,water pressure or other external force,subgrade filling from the settlement joint erosion,influence the stability of roadbed and structures.The settlement structure abutment back soil pressure grouting,the abutment soil as a whole,forming the structure of lateral supporting platform,which can effectively solve the stability problem of the roadbed and structures.
