摘要
天津港盐码头横梁近半数发生不同程度的开裂,裂缝位置多在三跨连续梁中跨的1/3跨长附近,这种裂缝一般不常见。本文为弄清其开裂原因及能否维持码头的安全使用,作了盐码头现场荷载试验,并进行了理论计算,分析了开裂原因并确定了维持盐码头使用的荷载大小。
Almost half of the crossbeams of the salt wharf of Tianjin Port have cracked in different degrees. The locations of most cracks are at about 1/3 mid—span of the three—span—continuous—beams. This kind of cracks is not common. To make clear the causes for cracking and if the wharf can be used in safety, the load—test of crossbeams was performed on site and the theoretical analysis was also made. The load magnitude to maintain the use of the salt wharf is given in this paper
