高填方场地回填土施工质量控制

Construction quality control of backfilling soil in high filling field

结合具体工程实例提出高速公路服务区高填方路基和场地回填土的施工方法,综合采用片石挤淤、分层碾压和重锤夯实的技术措施消除黄土湿陷性,提高地基承载力和减小沉降变形,保证了服务区道路和建筑物的稳定性,对同类工程具有指导和借鉴作用。

Combining with specific engineering examples, the article puts forward construction methods of high filling subgrade and field back fill- ing soil in highway service area, comprehensively applies flag packing, hierarchical rolling and heavy tamping measures to demolish collapsible loose. As a result, it improves the foundation bearing capacity, reduces subsidence deformation, and guarantees the highway and building stabili- ty in service area, which plays certain guiding role for similar engineering.
