摘要
重力坝一直都是水利水电工程建设的重点.高温炎热条件下,碾压混凝土重力坝很容易受到温度的影响,诱发裂缝施工问题,这样严重影响了工程的施工质量.同时,受到高温条件的影响,碾压混凝土重力坝温控防裂工作的难度相对较大,所以需要结合实际情况,通过对裂缝机理的了解,根据裂缝的成因,采取合理、有效的防控措施,以此保证碾压混凝土重力坝施工的质量,降低裂缝问题的产生.本文基于此展开分析和阐述.
Abstract
Gravity dam has always been the focus of water conservancy and hydropower project construction.In high temperature and hot conditions,the roller compacted concrete gravity dam is easily affected by the temperature,which induces crack construction problems and seriously affects the construction quality of the project.At the same time,due to the influence of high temperature conditions,the difficulty of temperature control and crack prevention work for roller compacted concrete gravity dam is relatively great,so it is necessary to combine with the actual situation,and take reasonable and effective prevention and control measures according to the cause of the crack through the understanding of the crack mechanism,so as to ensure the quality of roller compacted concrete gravity dam construction and reduce the occurrence of crack problems.Based on this condition,this paper analyzes and elaborates these issues.
