浅析横向力系数作为水泥路面交竣工验收阶段控制指标的必要性

The Analysis on the Necessity of Taking Sideway Force Coefficient as the Control Standards for Concrete Pavement at the Handover and Completion Acceptance Stage

以某条高速公路为依托工程,在其交工验收阶段,将两段构造深度不合格的隧道水泥路面作为研究路段,相邻路段作为比对路段(研究路段、比对路段统称为试验路段),在交竣工验收期间对试验路段横向力系数和构造深度进行跟踪检测,并对结果进行分析,得出横向力系数与构造深度没有直接关系,竣工验收阶段路面构造深度不满足要求,但是路面抗滑性能评价等级仍为"优良",因此在水泥路面交竣工验收阶段不应将构造深度作为水泥路面抗滑性能评定的唯一标准,而应将横向力系数作为判定路面抗滑性能合格与否的标准。

Relying on an expressway, two sections of tunnel concrete pavement that were unqualified in structure depth were taken as the research road section and the adjacent road section was taken as the comparative road section （research road section and comparative road section are called as trial pavement section collectively） at the handover acceptance stage. During handover and completion acceptance stage, tracking detection was conducted for the sideway force coefficient and structure depth of trial pavement section, and the results were analyzed simukaneously. It is concluded that there was no direct relation between sideway force coefficient and structure depth. The pavement structure depth at completion but the evaluation grade of pavement anti-skid performance acceptance stage couldn＇t satisfy the requirements, was still ＂excellent＂. Hence, the structure depth couldn＇t be taken as the sole standard for assessing the concrete and completion acceptance stage for concrete pavement, but the standard to judge whether the pavement anti-skid performance is pavement anti-skid performance at the handover sideway force coefficient should be taken as the qualified or not.
