The influences of mountainous highway construction on ecological environment and its protective measures;

On how to reduce the project cost of mountainous highway on the design stage;

Quality control of mountainous highway security protection project construction

Protection designs for mountain highway roadbeds against flooding;

Physical Modeling Study on Lower Slope of Mountain Road Water Damage;

With more and more highways being constructed in mountain areas these years,it is increasingly important to ensure the safety of mountain roads.

The roadside accident frequency is higher in mountainous area highway,this is concerned with lacking protection facilities.

According to the geologic structure,formation lithology and the hydrogeology of the mountainous area highway landslide,the calculation and analysis for the stability of the landslide were performed under the consideration of two kinds of water content with slope limit equilibrium analysis and Flac technique.

Application of the used-for-bridge pool as a protection for bridges culverts across mountainous roads;

Application of asphalt mirco surface in mountainous road;

In construction of highways in mountainous area,the preliminary design stage often faces comparison and selection among multiple plans.

According to the highways in mountainous area are easily destroyed by flood,it analyses the reasons of highway in mountainous area being destroyed by flood from design limitation,climate and geological condition,and puts forward detailed measures to prevent highways in mountainous area are destroyed by flood from design and maintenance,so as to enhance disaster preventing and resisting ability.
