摘　　要：针对桥梁工程现浇梁支架采用的碗扣支撑架施工,阐述了通过施工总荷载值快速和初步判定支撑架横距、纵距及步距的方法,减少了多次重复进行间排距布置及校核工作量,该方法简单易懂且在实践过程中经过验证,能够满足承载要求,安全可靠,具有较好的实用性,尤其是在投标过程中能够快速、准确、合理地计算支撑架工程量,值得类似工程借鉴和推广。This paper expounds the method for quick and initial determination of the horizontal,longitudinal and step distances between the support frames through the total load value during construction of cast-in-place beam bridge applying full bowl-type brackets.The method introduced in this paper reduces the repeated arrangement and checking of row spacing and is easy to be understood.It is verified by engineering practice that this quick determination method meets the load-bearing requirement,and it is safe,reliable and has good practicability.Especially when it is used during bidding process,the quantity of support frames can be quickly,accurately and reasonably calculated.This method is worth of being referenced and popularized in similar projects.
