Abstract
In this paper, the geological condition of the right-side slope of the K114 + 694–K115 + 162 section of Yong-tai-wen Expressway is investigated and analyzed with the results showing that the strength of rock mass is the main contributor to the stability of the slope. Then, two widening schemes are proposed, which are the steep slope with strong support and the gentle slope with general support schemes. The static/slope module of MIDAS GTS finite element analysis software and the strength reduction method were used to compare the two schemes. The results show that the steep slope with a strong support scheme has obvious advantages in land requisition, environmental protection, and safety and is more suitable for reconstructing and expanding the highway slope.
