水闸闸墩裂缝分析及预防控制措施探讨

结合工程实践，对水闸闸墩出现的裂缝，通过混凝土的裂缝机理的研究，从混凝土原材料、配合比、施工控制和养护等方面进行分析探讨，提出了对施工过程控制和增设构造钢筋等预防和控制措施，并在工程中应用实施，达到了控制裂缝出现的目的。

The Analysis of the Crack of Water Gate Pier and Discussion on Prevention and Control Measures

In accordance with the actual construction practice, the reason why the cracking happens on the pier surface of sluice was explored deeply, through searching the crack texture on concrete and from the aspects of concrete raw materials, concrete mix proportion, concreting work management, curing work of concrete, etc, some precautionary and control measures, such as strengthening the process control of concrete placement, and increasing the structural reinforcement in the concrete, etc, were proposed and application to the construction period for achieving the target of preventing the concrete crack.
