摘要
介绍了体外预应力的特点,从线形、锚固块、转向块、定位和防震装置等方面,阐述了体外预应力的设计关键点,并以某高速公路连续箱梁桥为背景,探讨了体外预应力的加固计算方法,验证了体外预应力加固的有效性。
The paper introduces the features of the external prestress,illustrates the key points for the design of the external prestress from the linear,anchor block,deviator,positioning and seismic equipment,explores its consolidation calculation methods by taking the continuous box girder as the background,and proves it is effective.
