路基公路最基本的工程设施,可以说是公路线形主体,是公路最重要的组成部分,路基的好坏从某种意义上说,就直接决定了公路质量好坏,坚固的路基能够有效保证公路使用寿命和年限,尽最大可能的减轻公路运输压力,能够防止路面变形、开裂,进一步保证行车安全。通过对路基施工特点的讨论,提炼出可行的施工管理要点,对路基施工、桥涵填土、路基施工、防护工程、挂线施工等方面均有借鉴作用。
Subgrade highway most basic engineering facilities, can be said that the main road alignment, highway is the most important part of the roadbed in a sense, the quality of the road directly determines the quality of the road, a solid foundation can effectively guarantee the road Service life and life span, try their best to reduce the pressure on the road transportation, to prevent the road surface deformation, cracking, to further ensure traffic safety. Through the discussion of the characteristics of subgrade construction, the feasible construction management points are extracted, which can be used for reference in roadbed construction, bridge and culvert filling, subgrade construction, protection engineering and hanging construction.
