Application of Geocell in Cold Regions Canal Slope Protection

E. L. Wang, X. C. Liu


Heilongjiang province is the lowest temperature provinces in China, the cold environment cause the freeze injury of the hydraulic engineering, the soil slopes of larger canal often collapse, so there are many difficulties in the water transmission of irrigation and draining canals and the engineering maintenance management. Through field surveying, combined with the environment characteristics of cold regions, the damage characteristics and main reasons of soil slope were concluded. And the anti-freezing design practice was put forward, in order to protect the slope from being damaged. The geocell gravel structure was used in cold regions canal slope protection engineering project, through which the application effect of this structures was observed and evaluated. And the new way to protect the canal soil slope in cold regions was put forward.
