【摘要】 山区输电线路的岩石锚筋基础是环保、经济的新型基础型式,普遍采用HRB335、HRB400钢筋,钢筋屈服强度较低,而且当基础作用力大时,其经济性不明显。通过分析得到,高强度钢筋用于该种基础型式是可行的,而且经济合理、安全可靠、省材环保,并且可以使岩石的抗剪性能、岩石和砂浆的粘结强度、钢筋和砂浆的粘结强度得到充分发挥。更多还原

【Abstract】 Rock anchor foundation in transmission line is considered as a new type of foundation which is more environment protective and economical in mountainous areas. Steels of class HRB335,HRB400 are broadly used,but the yield strength is relatively low.Moreover,the economical efficiency is not obvious when the force of foundation is big.In this paper,it was found that the applying of high intensity steels on the current type of foundation is feasible,economical,safe,reliable, material-saving and environment protection as well.The application was found to allow full play to the shear performance of rock,the cohesive strength of both the rock and mortar,the cohesive strength of steel and mortar as well.更多还原
