摘要
道路桥涵施工中,路基施工相对于路面结构层、桥涵隧道是较容易被轻视的,而现今道路桥涵病害中最为常见的路面沉陷、纵裂,桥、涵洞头跳车却大部分都是由于路基沉陷引起的。通过大中修工程发现路基病害引起的维修费用远超过路面洗刨罩面、桥梁加固等,因此必须转变观念、重视路基施工管理。
Relative to the pavement structure layer and bridge culvert tunnel,the onstruction of roadbed is easier to be ignored in road and bridge construction process.Today,the most frequent sign of highway pavement pression,pavement crack,bridge bump,culvert bump are caused by the subgrade settlement.Through the large and medium sized construction project,we found that the subgrade diseases caused by the repair cost are far outside pavement planer cover face wash and bridge reinforcement.So,we must transform idea,attraches importance to subgrade construction management.
