| dc.description.abstract | Taiwan has a mountainous terrain and complex geological conditions. It is also located in the Pacific Rim Seismic Belt and has frequent earthquakes.
Under the historical and cultural background, the development of mountain slopes and the opening of mountain roads are extremely common.
In recent years, due to climatic changes, heavy rains, and severe typhoons, it has caused a greater risk of disasters on the originally fragile mountain road slopes.
Road slope disasters have become one of the main natural disasters in Taiwan, and once they occur, they will affect people’s lives and property enormously.
Therefore, how to improve the efficiency of disaster rescue and maintenance and management of mountain roads and reduce the risk of disasters has become an important topic of disaster prevention and reduction.
This study takes the 0k+160 slope disaster of Tao 112 Line, Fuxing District, Taoyuan City as an example. Using the STABL limit equilibrium method, commonly used in the industry to analyze slope stability, and compared the commonly used methods of slope treatment, anchored high tension wire mesh and sprayed concrete girder, and provide a reference for the selection of construction methods, while maintaining safety and stability, consider the cost, timeliness, period, construction, environmental protection, and durability to achieve the best engineering benefits.
It is hoped that through the induction and analysis of this research, the practical cases and numerical analysis experience of slope stability will be improved, provides the front line maintenance personnel a basic reference, the best method for restoration, to minimizes the impact of disasters, constructs safe roads. | en_US |
