خلاصه مقاله:
Since, complete protection against local scour around bridge pier are noteconomical, the designer must seek ways to steer and control scour andreduce scour potential of structural damage. Usually two basic methods toprotect against scour are presented. In the first way, that called directmethod resistance of river bed is added against stresses. In the indirect way,second method, the flow regime has changed and horse shoe and vortexeswhich created around bridge pier are wreaked and reduce its intensity. Oneof the cases of the 2nd way is using the slot in the pier .The research hasshown that this slot which construct in the pier can reduce depth of scourhole about 20%. But the slot, causes reduce the strength of pier structureunder applied load up to 55% strength of control model. In this researchseek a way for solving the problem. After carryout many tests found thatwhen used the rectangular tie in section of slot, pier gain the strength about86.4% of control model. Therefore, approximately comport 310.98kg/cm2.
