摘要
某水利枢纽工程导流洞堵体混凝土施工具有工期短、强度大、负温施工期长和自然降温困难等特点,针对上述特点,经过仔细的分析论证,导流洞封堵体的施工控制参数较原设计值进行了适当提高。根据监测资料显示,堵体混凝土运行性状良好,满足设计功能要求,对同类地区水工隧洞堵体的设计与施工具有一定的借鉴意义。
The construction of the bulkhead of the diversion tunnel for a water control project has the characteristics such as short construction period,more working intensity,long period of construction under the subzero temperature and difficult to lower temperature naturally;for which the control parameters for the construction of the bulkhead are properly increased compared with the original design values after the careful analysis and demonstration concerned.The monitoring data show that the concrete of the bulkhead has a better operation behavior to satisfy the requirement on its designed function,and then has a certain reference value for the bulkhead of the hydraulic tunnel within the similar region.
