Abstract
The stability of a slope at post-construction stage is largely depend on the resistance force of the soil to whitsand againts the driving force. One of the most common driving forces found in tropical climates is rainfall. The progression of climate change leads to the change of rainfall pattern with the occurrence of heavy precipitation in shorter periods of time. Over the past four years, 30 landslides have occurred on the XY Toll Road. To prevent further landslide, an inspection was conducted in accordance with the Hong Kong Geo Office Guide for drainage inspection and maintenance. The inspection was conducted in 2 months along 100 km of toll road. The inspection result in 2024 indicate that 88 slopes have undergone varying degrees of erosion, varies from mild to severe. Reffering to the inspection result on existing slope drainage condition, all slopes have a vulnerability value of 8. Once the inspection activities are completed and the condition of each slope is determined, a landslide prevention strategy can be developed. Proposed prevention strategies include vegetation control, drainage channel cleaning, and channel repairs. It is essential to conduct routine monitoring of the drainage channels under both normal and extreme rainfall conditions to guarantee optimal drainage performance. Regular inspections of drainage channels as stated in the slope management system can help slope managers to minimize the risk of instability caused by rainwater.
