摘要
黄土地区路基防护与支挡工程主要病害有勾缝脱落、裂缝、表面破损、墙背填土沉陷变形及黄土陷穴、基础冲刷淘空、泄水孔堵塞、沉降缝(伸缩缝)变形破坏等形式。经总结分析,提出了增加排水设施、充分夯实脱空区域、及时检查修补、处治黄土陷穴等关键措施,并提出了黄土地区路基防护与支挡工程设计中可供选择的与防护支挡方式及关键技术。
The main diseases of subgrade protection and retaining engineering in the loess area has different forms such as pointing fall-off, crack, surface damage, settlement deformation of fall behind retaining wall, loess settlement cave, scouring foundation, blockage of the weep hole, deformation failure of settlement/expansion joints and so on. After analyzing and summarizing, some key measures were put forward, including increasing drainage facilities, sufficient compaction in the cavity area, timely examining and repairing, treatment of the loess settlement cave etc. Some protection and retaining forms and key technologies available for selection during the engineering design and the associated issues for attention were also provided.
