摘要
高速公路红砂岩路基若按路基施工规范的方法进行施工并控制施工质量比较难,而根据实践开辟另一种施工方法,可以有效地控制施工质量,节省施工成本。另外,对红砂岩路基可能存在的沉降造成的路面裂缝采用注浆加固技术,可在事前事后有效处理我国南方红砂岩填筑施工难的问题。
It is difficult to control the construction quality of red sandstone roadbed according to the construction method provided by the roadbed construction specifications.Therefore,another construction method is put forward based on engineering practice,which can control the construction quality effectively,and save the construction cost.Using grouting reinforcement technique can treat the pavement crack of red sandstone roadbed resulting from the exiting settlement,which could effectively handle the problems of difficult construction of red sandstone roadbed in South China.
