摘要
面层混凝土裂缝是码头工程的质量通病,严重影响着码头的整体观感及结构耐久性,必须有针对性地对裂缝形态及成因进行研究,并采取有效的控制措施。介绍了华南某高桩墩台式码头的构造设计及施工工艺特点,分析码头面层结构各类混凝土裂缝的形态特征及分布情况,并通过模拟计算混凝土结构的温度与应力,分析各类裂缝的成因。结合码头的具体施工工艺提出了针对高桩墩台式码头面层混凝土裂缝的综合控制措施。
This study investigated the definite forms of several kinds of cracks, analyzed and discussed the cause of each kind of cracks according to the current situation of the cracks on surface layer of the dolphin type berth on high piles. Then put forward the measures for prevention and control of the cracks on wharf surface according to the specific situation of the construction.
