Capillary barrier system (CBS) was developed as a slope protection method to prevent rainwater infiltration into the underlying soil based on principle of unsaturated mechanics by harnessing distinct difference in hydraulic properties fine-grained layer with those coarse-grained soils. The CBS is commonly designed and constructed using gravel material fine sand material. However, due scarcity n...

The study of highway ecological slope protection in the Tibet Autonomous Region my country is still its infancy due to factors such as climate and topography. This article introduces main technology application scope highway, analyzes from perspective environmental characteristics various areas Tibet. highways explores existing problems puts forward suggestion that needs be combined with engine...

OBJECTIVES Potential environmental risks caused by chemicals that could be released from a recycled plastic product were assessed using a screening risk assessment procedure for chemicals in recycled products. METHODS Plastic slope protection blocks manufactured from recycled plastics were chosen as model recycled products. Ecological risks caused by four model chemicals -di-(2-ethylhexyl) ph...

An analysis of the current situation ecological slope protection is conducted to obtain a more optimized scheme, in which major factors influencing effect constitute object analysis. Based on optimum grass seed combination, and legume plant matching with better growth effects are chosen, mix proportion plant-growing medium best for determined, reflecting application plants providing reference s...
