摘　　要：为了解哈尔滨绕城高速群力互通处加筋土挡墙的使用性能,制定挡墙检测方案,并对挡墙面板变形、路面沉降及挡墙内部质量进行检测。通过检测可知,挡墙面板局部存在较大的弧形外鼓和整体外倾病害;挡墙路面均存在不均匀沉降,最大沉降量接近29cm;挡墙内部出现严重的不密实区,且病害面积最大达到4m2;挡墙内部筋带出现较严重的弯曲变形,右幅筋带变形尤为严重;最终对该段挡墙评定为C级。By detection of the reinforce retaining wall of Harbin beltway Qunli interworking section,a retaining wall detection program is formulated,of which the deformation of retaining wall,pavement settlement and the internal quality are also detected.The detecting result shows that there is a large curved outer drum and overall extraversion in local retaining wall.Uneven settlement appears in the retaining wall pavement when the largest settlement is close to 29 cm.Some part of the internal retaining wall is not dense area,and the disease area maximum reaches 4m2.When the retaining wall with internal ribs appears with more serious bending deformation,the deformation of right side bar strip is particularly serious.The grade of this retaining wall is assessed as C-level.
