摘要
结合湖南省对口援建项目——理县至小金公路工程中的豹子嘴岩质边坡,依据正交试验设计原理,以FLAC3D数值计算法和数理统计为手段,对影响岩质边坡地震稳定性的5种因素参数进行了敏感性分析.通过极差分析和敏感性趋势图,得出了岩质边坡地震稳定性对各影响因素的敏感程度,对震区岩质边坡设计和施工提供了理论依据.
Combining with the Baozizui rock slope in the highway project of Lixian to Xiaojin for rebuilding project supported by Hunan Province and according to orthogonal design principle, five types of factorial parameters that influence the seismic stability of rock slope are analyzed in sensitivity by means of FLAC3D numerical calculation and mathematical statistics. Based on different analysis and the sensitivity analysis trend chart, the sensitivity degree of the seismic stability of rock slope to the five factors is deduced to provide a theoretical basis for the design and construction of rock slope in earthquake region.
