泡沫轻质土在杭州东站软土路基地基处理中的应用
Research on Foundation Treatment of Soft Soil Subgrade of the East Hangzhou Railway Station Building
摘要
Abstract
The problems of post-construction settlement of soft soil subgrade and ineffective compaction quality due to confined working face and complicated working condition in the construction of the east Hangzhou railway station building can not be solved by the conventional treatment methods and a new material of foamed lightweight soil selected after comprehensive comparison is applied to the treatment of soft soil of railway subgrade. The results of the settlement monitoring of soft soil show that the replacement of foamed lightweight soil can effectively reduce additional stress and subgrade settlement after construction,and improve embankment compaction quality in the narrow working face. Research results show that the replacement of foamed lightweight soil is an effective way to treat soft soil of railway subgrade and sees wide application.关键词
