摘要:
本文根据同三线宁波高速公路试验段施工经验,阐述了软土地区高速公路施工中路基宽度不足的原因,提出了有关路基施工中逐层加宽的计算公式以满足路基断面的设计要求,可供软土地区修筑高速公路参考。

Abstract:
Based on the construction experiences of the Ningbo test section of Tongsan express highway, in this paper described the causes of the insufficient subgrade width in construction of express highway on soft soil area, presented the calculating formula of layered widening in subgrade construction, so as to meet the requirement for design of subgrade section, it may be used as reference for building express highways in mollisol region.
Key words:  soft foundation, short of width, widening value,
