摘　　要：早期的高速公路大部分按双向四车道建设,无法满足当前的交通需求,因此出现大量拓宽路基,同时拓宽路基与原有路基由于差异沉降等原因容易导致路面开裂,由于雨水从裂缝处渗入等原因而影响路基的稳定性,以常见路基拓宽方式和典型路面结构为例,分析了面层是否开裂和新旧路基结合状况对路基稳定性的影响,并详细介绍了相应状况稳定性的分析方法。Most of the early highway construction,according to four lanes can't satisfy the current traffic demand,so appear a large number of widening roadbed,at the same time the broaden subgrade and the old subgrade due to reasons such as differential settlement is easy to result in the crack of the pavement,due to reasons such as rain water seeping into the cracks,the stability of the subgrade is affected,based on the common roadbed broaden way and the typical pavement structure as an example,The influence of surface cracking and the combination of old and new road on subgrade stability is analyzed,and the analysis method of corresponding condition stability is introduced in detail.
