摘　　要：预制梁(板)架梁安装过程中,需在已安装的裸梁上运输不同重量的预制梁(板)。目前,炮车运梁已在工程中大量采用,但有关炮车运梁安全性的系统论证不够完善。本文通过理论计算及实桥试验,对炮车运梁的安全性进行评价,并在此基础上提出相应的安全保证措施,以保证架梁施工的安全。In the course of assembling of precast beams（or slabs）,it is necessary to carrying the precast beams（or slabs） with different weights on the assembled naked beams.At present,carrying beams using the special vehicle is widely used,but there are few systematic studies on the safety of carrying beams.In this paper,the safety evaluation for carrying beams using the special vehicles is performed through the theoretical computation and the tests.Based on the work,the measures for safety are presented to ensure the safety of carrying beams.

关 键 词：先简支后连续桥梁 预制梁架设 裸梁 安全性
