| Summary: | 碩士 === 高苑科技大學 === 土木工程研究所 === 107 === This study explores the effectiveness of governance method mudstone forward slope with the on-site monitoring information of 360K to 364K on the north side on the Third National Highway of southern Taiwan in recent years.
The slopes of this section were originally disposed of with ground anchors. Due to multiple wind disasters, they were used as row piles and stone cages, which achieved good results. This study began to compare the data monitored in the field from 2011 to 2018 years, and cooperated with the results of the PLAXIS program analysis to understand its influence on slope stability and mechanical behavior of row piles and ground anchors, as a reference for the stability design of slopes in the characteristics of mudstone forward slope.
According to the analysis results, the possible sliding surface obtained by the program analysis is consistent with the possible sliding surface obtained from the field monitoring data. The effect of the ground anchor on stabilizing the slope of the mudstone is weakened with the use period, and the method of row piles is relatively stable.
