PRESENT STATUS AND DEVELOPMENT OF GROUND ANCHORAGES

The ground anchorages is a key branch of the geotechnical engineering The strength and stability of rock and soil can be enhanced The advantage is to decrease the self?weight of structure,to save the engineering materials,and to benefit the cons truction safety The development of ground anchorages is reviewed throughout the country and world in the paper It includes the new achievements of ground anchorages,the application of anchoring in weak soil,and the multiple soil nailing Some suggestions on the key problems of the development of ground anchoring technology in China are also discussed Such as the design and experiment,the corrosion and protection,as well as the directions of research are also presented in the paper
