摘要
文章针对道路拓宽路基差异沉降引发的路面开裂问题展开探讨,详细分析了道路拓宽过程中路基沉降以及路面开裂原理。并结合实际情况,分析了不同因素对于路面开裂的影响,主要包括新旧路基沉降、结构层材料、拓宽宽度以及路面厚度4个方面,提出了道路拓宽工程中路面抗裂设计要点。根据研究结果可知,通过合理进行路面结构设计、加强新旧路面拼接设计,以及强化差异沉降控制,能够有效实现对于道路拓宽路面的抗裂处理和预防,提高路面工程质量。
For road widening subgrade settlement of pavement cracking problems,detailed analysis of the road widening engineering process,subgrade settlement and pavement cracking principle,and combined with the actual situation,analyzes the influence of different factors for pavement cracking,mainly including the old and new roadbed settlement,structure layer material,widen the width and the pavement thickness of four aspects,finally put forward the road widening engineering pavement crack resistance design points.According to the research results,through the reasonable pavement structure design,strengthening the new and old pavement splicing design,and strengthening the differential settlement control,can effectively realize the crack resistance treatment and prevention,and improving the quality of pavement engineering.
