Problems were discovered in two prestressed construction works while the “Yahua” anchorage wasused.

Experimental Research of capacity performance of bonded prestressing tendon embossing anchorage

Based on the force balance of anchorage segment,the distribution functions of shear stress and axial force of anchorage segment of pressure-type cable,which are hyperbolic functions,are derived utilizing perfect elastoplastic load-transfer model and the displacement mode of interaction between grout mass,cable and anchorage mass.

Under the conditions of weak soil stratum and complicated soil property,utilizing the structural characteristics of dispersed compressing anchor rope and taking comprehensive measures including soil anchor experiment,design optimization,as well as construction technology improvement,the designed bearing capacity is assured,which is of great significance for the application an.
