| dc.description.abstract | The mountainous terrain of Taiwan is steep, geologically fragmented, and seismically active. In recent years, under the influence of global climate change and extreme weather, heavy rainfall, and typhoon rain have increased dramatically, resulting in a relatively higher probability of natural disasters.
Rockfalls and landslides occur in mountainous areas, causing damage to road facilities and interruption of traffic, which have a huge impact on people′s living, lives, and property. The construction of safe roads is the most important issue at present.
The causes of various slope disasters are not the same, the selection of reconstruction methods after slope disasters should consider various disaster-causing factors, and choose the most appropriate reconstruction plan to effectively suppress the recurrence of slope disasters.
This research collects the cases of slope disasters at Provincial Highway 7 within Taoyuan City, the section from 0K to 61K, starting from the year 2007 to the present, and analyzes the causes and types of disasters.
Interviews were conducted with former or current maintenance engineers and supervisors of Provincial Highway 7, determining factors to be considered during disaster recovery and suggested repair methods for different disaster types.
It is hoped that the induction and analysis of this research can help the slope maintenance in mountainous areas, provide the first line maintenance engineering the basic reference basis, and determine the best recovery plan when facing the slope disaster recovery plan, minimize the impact of disasters, and construct safe roads. | en_US |
